SENNHEISER HE 1: A SINGAPORE EXCLUSIVE REVIEW



SENNHEISER HE 1: A SINGAPORE EXCLUSIVE REVIEW 

Nothing could prepare me for the experience I received from listening the Sennheiser HE 1 headphone system priced at €50,000. Earlier this year, I attended the CanJam 2016 Singapore and tried the Sennheiser Opheus HE 90, which was the best headphones system, until Sennheiser created the HE 1, becoming the NEW headphones system in the world. After listening to quite a handful of premium headphones, I wonder how much better can the HE 1 offer. Can a pair of headphones deliver any clearer sounds that what I have already heard in expensive headphones?
The private listening session was held at a hotel suite in Marina Bay Sands. After spending some time taking photos, I started off with 3 mandatory listening tracks curated by Sennheiser, digitally streamed from the iMac via USB.
The first track was “Strive” by Amber Rubarth, a binaural recording, which means it was recorded with 2 microphones to mimic the human ear, resulting in a 3D audio experience. The second track was “Somewhere, Somebody” by Jennifer Warnes. The final track was “Money for Nothing” by Dire Straits.
I went on to request for other tracks. I started off with “Hotel California” live by Eagles in their CD collection. I then requested to listen with my personal CD, “The Magnificent Seven” and “Also Sprach Zarathustra” from Erich Kunzel and the Cincinnati Pops Orchestra, brilliantly recorded and engineered by Telarc label.

The HE 1 is not all about the dynamics, details and clarity which most premium headphones already possess. That’s not what made it especially good. It’s the aural spaciousness and the unrelenting outpour of musical sounds with no physical, mechanical or electrical constraints.
I was amazed to find that there is so much aural space when I listen to tightly-layered tracks. The sound staging is not exaggerated from the original source, yet the instruments are distinct. For lightly-arranged music tracks, you can almost feel the distance between the source (vocals, instruments) and the recording microphones. For loud passages with multiple instruments, most other headphones would sound crowded and somewhat compressed by the limitations of sound pressure. Yet the HE 1 is sensitive enough to produce the dynamic range effortlessly with no apparent strain. From the soft low rumble to the sudden loud entrance in “Also Sprach”, each instrument layer has its own space to play out to my ears.
To describe in lay terms, the treble is bright without sounding brittle, with great extension upwards to deliver airiness and clarity without exaggeration. The mid-high bass is musical without too boomy, while low bass has good response for the dynamic feel. The mids are not bloated, hence there is lacking of warmth, if that’s something that you prefer.
To sum up what’s so unique about the HE 1, it is the ability to deliver every instrument, every audio layer, in exact expression, from the attack to the aftertone. These characteristics are enhanced – not exaggerated – on the HE 1 to provide added natural dimensions to quality-recorded music.
I was very pleased that the Sennheiser HE 1 is worth the €50,000 price tag. Contact Sennheiser Singapore if you are interested to order a unit. Official product website: http://www.sennheiser.com/sennheiser-he-1

Sony Xperia XZ review

Sony Xperia XZ review

Introduction

Sony's latest flagship, the Xperia Z6 comes with refined design, improved camera, and a due update in specs. Wait, back up a little there - it's actually called the Xperia XZ this time around but, yeah, the rest of that is true.




When Sony announced the new X-series, some suggested that the Xperia X Performance was meant to take on the likes of the Galaxy S7's and HTC 10's, but we knew that couldn't be the case. Okay, 'suspected' might be more accurate there. Obviously, now we all know that the Xperia XZ is Sony's top-dog for this season, and the Z in its name quickly reveals its ancestry.
Indeed, the XZ has a lot in common with the Z5. The display, for one, is the same size and resolution as the last generation - not necessarily a bad thing, but the XZ also comes with 3GB of RAM - modern-day flagships will crack a condescending smile seeing that in the spec sheet.


No one will laugh at the rest of it, though - top-of-the-line Snapdragon 820 chipset, 23MP camera with a trio of focusing technologies and 4K video recording (one could think the Z is required for that, had it not been for the M5), high-res 13MP front camera, Type-C connectivity, fingerprint reader, IP68 rating, stereo speakers - name one thing missing.


Sony Xperia XZ key features

  • 5.2" 1,080 x 1,920px LCD display with 424ppi, X-Reality for Mobile, Triluminos technology; Gorilla Glass
  • Android OS v6.0 Marshmallow with Xperia launcher
  • Qualcomm Snapdragon 820 chipset: quad-core Kryo CPU (2x2.15GHz +2x1.6GHz); Adreno 530 GPU; 3GB RAM
  • 23MP Sony IMX300 camera, 24mm-equiv. f/2.0 lens, predictive hybrid laser/phase detection/contrast AF, IR sensor for white balance selection, SteadyShot, LED flash, dedicated hardware shutter key; 4K video recording
  • 13 MP front-facing camera with 1080p@30fps video
  • 32GB/64GB of built-in storage and a microSD card slot
  • Single and dual-SIM models (DualSIM has a hybrid slot shared with the microSD card)
  • LTE Cat.9 (450/50 Mbps); Dual-band Wi-Fi a/b/g/n/ac; GPS/GLONASS/Beidou, Bluetooth v4.2
  • Active noise cancellation with a dedicated mic; 24-bit/192kHz Hi-Res audio
  • 2,900mAh non-removable battery, QuickCharge 3.0 support, Qnovo adaptive charging, Battery Care smart charging
  • IP68 rating for dust- and water-proofing
  • Fingerprint sensor (market dependent), stereo speakers, USB Type-C port, 3.5mm headphone jack

Main shortcomings

  • 3GB of RAM when the competition has almost entirely switched to 4GB or 6GB
  • FullHD screen resolution not flagship-grade
  • Fingerprint recognition not available in the US

We're yet to see tangible proof that the RAM race leads to actual usability benefits, but if people were to reason that way, the industry would sit still. It would have been great though, if Sony could have gone with 4GB just to keep up with the times and avoid having reviewers write this paragraph and make them look bad. The extra 1GB can't cost that much, right?
The second count Sony might end up countering with a sequel to the UltraHD Xperia Z5 Premium - 1080p for the mainstream flagship, 2160p for that supposed Premium, and no 1440p at all. Makes sense.

Finally, once again, Americans are denied fingerprint recognition. The hardware is there, apparently the paperwork isn't, so Sony can't offer the feature on the US market. We do have it on our international version review unit, and we'll test it for the rest of you to know, but not before we take a look at the hardware on the following page.

Meet Salto most vertically agile robot ever

Jumping Robots Mimic Adorable Big-Eyed Primates


A jumping robot — whose design was inspired by small primates known as bush babies — can spring off walls to gain height faster than any previous robot and could one day help rapidly scan urban disaster zones, researchers say.

Despite being just 10 inches (26 centimeters) tall and weighing only 0.2 pounds (100 grams), the one-legged robot, named Salto, can leap up more than 3.2 feet (1 meter) high from a standing position.
Salto is not the highest-jumping robot out there — some bots can jump to heights of more than 10 feet (3 meters), but those bots have to wind up for several minutes before they leap, whereas Salto can jump again almost immediately, the researchers said. This allows the one-legged bot to push off a wall — much like human parkour enthusiasts — to gain height more quickly, they added. [The 6 Strangest Robots Ever Created]
Salto is also able to climb at a rate of 5.7 feet per second (1.75 meters per second) compared to the 3.7 feet per second (1.12 m/s) achieved by the next-best robot, the researchers said. Salto's climbing rate is slightly better than a bullfrog’s, and it has 78 percent of the capabilities of the tree-dwelling bush baby that it’s modeled on, according to the scientists.
The idea for the robot came to the researchers after they spoke to first responders at an urban search-and-rescue training site in Menlo Park, California, said study leader Duncan Haldane, a robotics Ph.D. student at the University of California, Berkeley.
"Our goal was to have a search-and-rescue robot small enough to not disturb the rubble further, and move quickly across the many kinds of rubble produced by collapsed buildings," Haldane told reporters in a news conference on Monday (Dec. 5). "To do that, it has to be able to jump — and jump more adeptly — than prior robots."
Haldane and his colleagues looked to nature for inspiration, "because it's fair to say animals can outclass any robot when it compares to jumping," he said.
Before they could find the animal that would be the perfect model for their robot, the team had to develop a better measure for jumping ability. The researchers came up with a metric called "vertical jumping agility," which combines how high an animal or robot can jump with how often.
The Senegal bush baby (Galago senegalensis) scored highest in the scientists' tests, leaping from branch to branch at 7.2 feet per second (2.2 m/s). The animal gets its jumping prowess from its ability to get into a superlow crouch before takeoff — a feature that it shares with other jumping animals, the researchers said.
This allows the bush baby's leg muscles to store energy in elastic tendonsbefore releasing it later in the jump to generate 15 times more power than the muscles could alone, they added.
Translating this principle into a robotic system required some tinkering, though, Haldane said. [7 Cool Animal-Inspired Technologies]
"When you are doing bio-inspired engineering, you have to drastically simplify what you are seeing in nature and figure out the fundamental principles of what's going on," he said.
In place of a tendon, Salto the robot features a latex spring that's connected to its motor, which can be twisted to store energy. The configuration of the eight bars that make up the robot's leg means that the leverage it provides changes as the robot moves through the jumping motion, the researchers said.
At the beginning of the jump, while the robot is in a superlow crouch, there is little leverage, so power from the motor goes into twisting the spring rather than pushing off from the ground. As Salto's leg extends, the leverage increases, causing it to push off the ground and release the energy stored in the spring, according to the researchers.
"A crowbar provides you with a lever arm to generate a large prying force by exerting a small force at the end of the lever. It's a force multiplier," said study author Mark Plecnik, a postdoctoral scholar at UC Berkeley. "This is like using a crowbar that grows and shrinks as you are pushing on it."
Sensors on the robot allow it to keep track of its body angle, leg position and motor position, enabling the robot to adjust its angle in flight using a weighted tail so that it hits the wall at the right angle to allow it to spring off again.
Auke Jan Ijspeert, who leads the Biorobotics Laboratory at Ecole Polytechnique Fédérale de Lausanne in Switzerland, praised the group's innovation.
"Being able to fight against gravity is always a big problem for terrestrial animals and robots," Ijspeert told Live Science. "Such a system could be useful for applications in field robotics, for example, for search and rescue, pollution monitoring, inspection or agriculture."
The research team that designed Salto hopes that their vertical-agility metric will also help other scientists who are studying jumping animals, said Ron Fearing, a professor of electrical engineering and computer sciences at UC Berkeley, who oversaw the research.
Thomas Roberts, a professor at Brown University who specializes in biomechanics, thinks that it will, but he also thinks that the technology itself could be important for biologists.
"This is a great example of how bio-inspired engineering design can help us build novel devices, but also inform our understanding of biology," he told Live Science.
"In biology, we can only study animals that exist, and we generally assume that systems in nature work pretty well," Roberts said. "Roboticists can test this assumption by building mechanisms that are similar to biological systems, but depart in important ways."

Sony A6500 Review -- Now Shooting!

                                                                                                                                                                        
Sony A6500 Review -- Product Image
Sony's APS-C lineup has a new flagship camera, the Sony A6500. While it shares the same 4D Focus autofocus system as the A6300, the A6500 features vastly improved continuous shooting capabilities thanks to an expanded buffer and a new front-end LSI chip. The sensor inside may offer the same 24.2-megapixels of resolving power, but it is now accompanied by in-body 5-axis image stabilization, a first for a Sony APS-C camera.
Other updates in the Sony A6500 include a touch-screen display that allows for intuitive subject selection even when shooting through the viewfinder, a subtly restyled body for better handling, a revamped and more logical menu system and better high-sensitivity noise performance when shooting in JPEG mode.

Sony A6500 Field Test Part I

All the action from awesome Austin: Sony's enthusiast mirrorless camera gets a real workout


Sony A6500 review -- Sample photo
127mm-equivalent, 1/4,000 sec. @ f/2.8, ISO 200
Earlier this year, my colleague Jeremy Gray published his review of the Sony A6300, a followup to 2014's amazingly popular A6000. Now in double-quick time that camera, too, has a successor in the form of the Sony A6500. Recently, I was fortunate to shoot with the A6500 on a press experiential in Austin, Texas.
In all, I had three cameras on hand to shoot with during the week: The aforementioned A6500, the Translucent Mirror-based Sony A99 II and the pocket-friendly Sony RX100 V compact. With the A99 II in short supply, though, and the RX100 V perhaps not the most ideally-suited to the subjects on hand thanks to a relatively short lens, it was the A6500 with which I did the most shooting.
As is typical on a press experiential, Sony had plenty of great shooting subjects lined up to give all three cameras a good workout. After my first week with the A6500, I have to say that it acquitted itself might well, turning out a whole bunch of shots that I'm absolutely thrilled with!
The company also had plenty of glass for me to shoot with. In all, I used Sony's E 10–18 mm F4 OSS, Vario-Tessar T* E 16-70 mm F4 ZA OSS, FE 70-200 mm F2.8 GM OSS and FE 85 mm F1.4 GM lenses. Given the subjects on hand and my desire to bring them up close, the bulk of my shooting was with the 70-200mm optic, with the 85mm and 16-70mm lenses together taking the bulk of the remainder.

What's new in the Sony A6500?

But let's not get ahead of ourselves: I'll start from the beginning with my initial impressions on the physical design of the A6500.
Sony A6500 review -- Sample photo
127mm-equivalent, 1/4,000 sec. @ f/1.4, ISO 100
Were you to compare the Sony A6500 side-by-side with the A6300, I doubt that any differences would instantly leap to your attention. (I didn't have both cameras side by side, however, so I've had to base my own comparisons on memory and our photos of the earlier camera.)
A reprofiled, more comfortable grip and more controls
Looking at the two cameras' bodies, the most obvious change would likely be the handgrip, which has been reprofiled for greater comfort and a more secure grip, especially when shooting with longer lenses. It's both a little less wide and flat-fronted than before, and also just a touch deeper.
With the grip now narrower than before, there was no longer sufficient room for a control alongside the shutter button and the power switch which encircles it. That being the case, Sony's designers moved the existing Custom 1 button to the top of the body directly behind the handgrip, and for good measure added another Custom button right alongside it. (This is now labeled as Custom 2, and one more such button remains on the rear deck, which is now Custom 3.)
Sony A6500 review -- Sample photo
145mm-equivalent, 1/1,600 sec. @ f/2.8, ISO 100
It's just a little trickier to reach these new custom buttons, in part because they're a little further from the shutter button, and also because they now sit on a slightly higher surface of the camera body. With that said, I still found them fairly comfortable to use once I'd familiarized myself with the new layout.
There's still no front dial, sadly
Sadly, Sony passed up an opportunity to add a front control dial to the body while it was reworking the grip. If I'm honest, I'd rather have seen the company gift a twin-dial design to the A6500, rather than adding another Custom button. The lack of that second dial was one of the main reasons I found myself preferring the much larger Sony A99 II body in terms of ergonomics, when I had the opportunity to shoot both cameras side-by-side.
Sony A6500 review -- Sample photo
105mm-equivalent, 1/2,000 sec. @ f/4, ISO 200
In other respects, though, I found the Sony A6500's control layout pretty good. Sony tells us that the controls themselves now have a better feel, and while I didn't have an A6300 for a side-by-side comparison, I found almost everything pretty satisfactory on this front. I could easily tell when most controls were pressed or turned, and had no issues with accidentally changing settings either.
The movie button is poorly placed, but otherwise handling is good
The biggest remaining concern for me on the control front is the movie button, which I still feel is very poorly placed. Mounted in the right side of the thumbgrip, it's in a position we've seen in a fair few of Sony's cameras, but I find that its location is both hard to detect by touch, it doesn't give much in the way of button feel when pressed, and because of its location, it tends to induce rotation in the camera body when pressed.
Sony A6500 review -- Sample photo
288mm-equivalent, 1/4,000 sec. @ f/2.8, ISO 500
It's difficult to hold the camera steady when starting or stopping movie capture, because while the fingers of your right hand remain curled around the grip, the palm of your hand has to move away from the body a little to let your thumb reach the movie button. That loosened grip is then exacerbated by the fact that your thumb is pushing sideways against the back corner of the camera body.
Of course, it's easy enough to edit the start and end off your video clips to resolve this, but I'd much rather see Sony relocate the movie button, preferably to the top deck alongside the shutter button.
Faster processing and a bigger buffer help the A6500 shoot for longer
After the subtle body tweaks, the most obvious change in the Sony A6500 for my money would have to be its improved burst shooting depth. Performance itself is unchanged, with the A6500 still manufacturer-rated at eight frames per second in Continuous Hi mode, or 11 fps in Continuous Hi+.
Hi+ mode improves performance by disabling the live view feed between frames, and instead simply showing the image just captured. The difficulty here is that since you're never seeing your subject's current position but rather where it just was moments ago, it can be tough to track moving subjects well in this mode.
I preferred instead to switch to eight frames per second shooting with the viewfinder refresh rate boosted to 120 frames per second from the default 60 fps, and image review disabled. Here, I could track subjects much more easily and really take advantage of the buffer depth.
Sony A6500 review -- Sample photo
124mm-equivalent, 1/2,000 sec. @ f/4, ISO 250
And that's what I did, shooting liberally in raw+JPEG mode and capturing long burst of frames documenting the action packed subjects Sony offered up, from rodeos and skateboard parks to tennis and lacrosse. Seldom if ever did I manage to fill the buffer, a testament to the processing performance improvement provided by the A6500's new front-end LSI and larger buffer memory.
Although burst performance is greatly improved, write performance isn't
Unfortunately, write performance was another matter. This has long been something of a bugbear for Sony's cameras, and the A6500 is no different. With no UHS-II compatibility, it can take a while for the A6500 to catch up after a burst and write your images to memory -- and until they're all written, they can't be checked for focus, exposure and composition.
You can now, however, at least review those images which have already been written to storage while you're waiting for the buffer to clear. And there's also now an indication on the display showing how many images are remaining in the buffer. That helps a bit with the watched-kettle-never-boils syndrome, giving you an idea of how much longer you'll have to wait before you can review those last images or access the camera's full capabilities.
Sony A6500 review -- Sample photo
127mm-equivalent, 1/4,000 sec. @ f/2.2, ISO 100
(I don't have the camera body in front of me to double-check as I'm writing this, but I do seem to remember noticing that at least some menus and features remain inaccessible until the buffer has been cleared. I will of course be checking that for certitude just as soon as the camera is back in my hands, at which point I'll update this.)
The revamped menu system isn't perfect, but it's a definite improvement
Since I've just brought up the menu system, now's probably as good a time as any to discuss the changes here. The menu still has a tabbed design with multiple menu pages grouped under each tab, and as many as six options per page.
The tabs themselves are now color coded, although those colors don't seem to have any real meaning to them: Some record-mode settings are under the first red tab, and more are under a second purple tab, for example. And there can be a lot of pages -- literally dozens of them -- under each tab, so it can take a little while to familiarize yourself with precisely where the functions you're looking for are to be found.
Sony A6500 review -- Sample photo
192mm-equivalent, 1/4,000 sec. @ f/2.8, ISO 160
However, the menu items themselves now seem to be grouped more logically. While there doesn't seem to be much rhyme or reason as to where any given group of settings will be located under the two record-mode tabs, you do at least get an indication of what the current screen full of settings will predominantly relate to -- autofocus or exposure, say -- and those settings are by and large grouped together in a fairly logical manner.
Really, the biggest thing missing now is for Sony to add a customizable menu of some kind where you can store those settings you most frequently use, along the lines of the My Menu option offered by rivals.

Finally, the Sony A6500 sports a touch-screen!

Also new on the user interface front is a touch-screen display, and this is a very welcome addition. The reason: It lets you quickly and intuitively select the primary subject in the scene. And it's not just when shooting at arm's length using the LCD monitor, either: You can also use it in what Sony calls "touchpad" mode when using the electronic viewfinder.
Sony A6500 review -- Sample photo
241mm-equivalent, 1/1,250 sec. @ f/2.8, ISO 100
By default, when you're shooting through the viewfinder only the right half of the touch-screen is monitored for input. The reason for this is pretty simple. When you raise the camera to your eye, your face will block the left half of the screen, and the touch panel might be unintentionally triggered by bumping it against your face. You can, if you prefer, make the touch area even smaller, or allow full-screen control even when shooting through the viewfinder.
The touch-screen functionality can be a little confusing for portrait shots
There is but one quirk to this design, but I stumbled upon it pretty quickly. If you turn the camera to shoot in portrait orientation rather than landscape, the active area of the touch-screen doesn't change. That means the active area of the screen is now the top half, while the bottom half is ignored -- but that doesn't really make much sense, given that both top and bottom halves of the screen are now equally reachable.
Initially, I thought that the touchpad functionality simply didn't work in portrait orientation. With the camera in this orientation, my thumb naturally fell on the disabled lower half of the screen. It wasn't until I stumbled on the menu item allowing you to select the touch area that I realized my mistake (and at the same time, the UI quirk.) I'd really like to see Sony change this behavior, whether simply by ignoring the touch area setting for portrait shooting, or by allowing the user to set a separate preference for this orientation.
The only other concern I had with Sony's touchpad implementation is that it is a bit on the laggy side compared to similar functionality from rivals. I found that when adjusting my focus point when shooting through the viewfinder, the on-screen indication consistently lagged behind my touches by about a quarter to half a second. It's not enough to be a problem, but enough to make the function seem less polished, given the Sony A6500's considerable performance in other respects.
Sony A6500 review -- Sample photo
150mm-equivalent, 1/1,000 sec. @ f/4, ISO 100
I'm hopeful that this lag can be reduced through firmware optimization; it's a brand new feature for Sony, and as new code I'd guess the opportunities for optimization are better than for a feature which has already been polished and honed over numerous iterations. But even if not, it's still a very useful and intuitive feature -- you just have to put up with the lag and remember the active screen area when in portrait orientation.

The Sony A6500 has swift and capable autofocus for its class

The A6300 was no slouch in the autofocus department, with its point-dense hybrid autofocus system gaining high points in our review both for its performance and tracking capability. The Sony A6500 shares basically the same AF setup as its sibling, and I came away thoroughly impressed with its autofocus performance, finding it more than up to the task of following subjects around the lacrosse field or during the rodeo, those being two of the tougher subjects I shot with the A6500.
Sony A6500 review -- Sample photo
190mm-equivalent, 1/4,000 sec. @ f/2.8, ISO 1600
With that said, the tracking functionality isn't infallible. I did find it had a tendency to get confused sometimes, and switch between different subjects when they came sufficiently close together. For example, during the rodeo segment of our shoot, one of the shooting opportunities was what I believe was referred to as "pole bending" -- think the horseback equivalent of slalom skiing. Horse and rider would take a run down a row of poles, zig-zagging back and forth to cross each pole on the opposite side to the last one. At the end of the run, the horse and rider would then return at full speed parallel to the poles.
This was one of several subjects where I found that, shooting with a relatively long lens, the AF tracking would sometimes lose the moving horse which I'd initially selected as the subject, and suddenly fixate on one of the stationary poles instead. Of course, I could let up on the shutter button briefly, put the horse and rider back under my selected focus point and then continue, but I doubtless lost a few shots to this behavior.
Sony A6500 review -- Sample photo
247mm-equivalent, 1/4,000 sec. @ f/2.8, ISO 1600
Still, no camera I've shot with yet is perfect in this respect, and the A6500 also returned many sharply-focused shots even as I stood just a few feet to one side of the horses' path, as they thundered towards (and right past) me at one end of the poles. I mention it more for completeness than anything. And not only was I panning to follow the horses, but also zooming to try and keep the framing as I wanted it, mostly shooting with a fairly long focal length as well to get the shots I was after. These were really challenging shots, and the A6500 performed remarkably well with them despite the occasional tracking issues.
Sony A6500 review -- Sample photo
127mm-equivalent, 1/200 sec. @ f/1.4, ISO 125
Great image quality too, although I've yet to try the higher sensitivities
The one thing I've not had a chance to do much of yet with the Sony A6500 is low-light shooting. This is definitely on my to-do list for my next field test, but at low sensitivities at least I'm very pleased with what I've seen so far. The Sony A6500's images are crisp and detailed, and showed great color with for the most part accurate exposure.
If you're looking through the gallery, which I highly recommend doing, note that the lacrosse shots (which are just a tad underexposed) are down to myself, and not the camera. At the recommendation of prolific sports shooter and Sony Artisan Patrick Murphy-Racey, who was on hand to offer advice, I shot the lacrosse practice using manual exposure, and erred on the side of not losing the highlights in the teams' predominantly white uniforms).
Having not yet shot much at sensitivities beyond ISO 6400-equivalent (and then under very difficult lighting), I can't yet assess Sony's assertion that the high ISO noise levels in JPEG mode have been improved. In other respects, though, I'm very happy with what I've seen thus far in the image quality department.
More to come soon in my second field test
And with that, I'll bring my first field test of the Sony A6500 to a close! Watch this space for more coming soon, and if you have any requests for specific features you'd like to see tested (or questions you'd like answered) in the second field test, don't be shy! Sound off now in the comments below, and I'll do my best to get you answers just as soon as the A6500 is back in hand...

Sony A6500 Overview

By Jeremy Gray | Posted: 
24-megapixel sensor should provide similar IQ as the A6300
The Sony A6500 features a 24.2-megapixel APS-C Exmor CMOS sensor. The sensor, like the one found in the A6300, includes a variety of interesting technologies to help provide superior performance. The sensor combines a large photodiode substrate and a particularly thin wiring layer (compared to previous sensors from Sony) which allows the sensor to collect light more efficiency. Additionally, the sensor utilizes quick-transmission copper wiring that aids the A6500 in capturing 4K and high-speed Full HD video.
The 3:2 ratio sensor records 6,000 x 4,000 pixel images in JPEG and RAW file formats, with the latter format being 14-bit RAW (although not uncompressed). Files can be recorded in sRGB and Adobe RGB color spaces and the camera includes 13 types of Picture Effects (including Posterization, Pop Color, High Contrast Monochrome and more) and Creative Styles such as Standard, Vivid and Sunset, all with contrast, saturation and sharpness adjustments available.
Not everything is the same as it was in the A6300, however, as Sony has made advancements to its BIONZ X image processing engine. A newly-developed front-end large scale integration (LSI) chip and an optimized image processing algorithm is stated to contribute to improved texture reproduction and image quality. In addition to better image quality, the A6500 is said to offer less noise, particularly in the mid-to-high ISO sensitivity range. The A6500's native ISO range is 100-25,600, but it can be expanded to up to ISO 51,200.

Sony A6500 adds in-body 5-axis image stabilization and more

The A6500 can compensate for five types of camera shake with its new in-body 5-axis image stabilization system, which is a first for an APS-C camera from Sony. The camera uses a "high-accuracy gyro sensor" to provide stabilization equivalent to five stops according to CIPA testing standards. By pressing the shutter release halfway, you can monitor the image stabilization effect through the viewfinder or on the rear LCD, which allows you to ensure accurate framing and focus. When using an E-mount lens that has built-in optical image stabilization, the camera body handles horizontal, vertical and roll axis compensation while the lens compensates for pitch and yaw.

Despite this addition, thanks to reorganizing the camera's internal components, Sony was able to keep the A6500 body roughly the same size as the A6300. With a battery and Memory Stick Pro Duo card included, the A6500 weighs approximately a pound (453 grams) and has 4.75 x 2.75 x 2.13-inch dimensions (120 x 66.9 x 53.3 millimeters). That's only 1.7 ounces (49g) heavier and 0.18 inches (4.5mm) thicker than the A6300; the other dimensions are identical.

Constructed from magnesium alloy, the body is designed to be durable and reliable. It isn't just the body that's been crafted for durability, however, as the shutter mechanism has also been tested up to 200,000 release cycles. Speaking of the shutter, Sony has added braking mechanisms and elastic material that are said to reduce vibration during shutter release. Unfortunately, top shutter speed is still 1/4000s, even with the electronic shutter.

To help you shoot in adverse conditions, the A6500 also includes dust and moisture resistance, including sealing around buttons and dials and a double-layered structure that creates tight locks between various components and panels. Borrowing from the A7 II series, the A6500 also includes a more robust lens mount.

Two of the Sony A6500's most notable body features relate to its displays. The 3-inch TFT LCD monitor on the rear of the camera now has a touch panel overlay. Sony shooters have been clamoring for better touchscreen integration in Sony's diverse camera lineup and the A6500 answers the call. The tilting display can angle up approximately 90 degrees and down roughly 45. When shooting through the camera's new electronic viewfinder (more on that in a moment), you can use the rear display to select a focus point using touch. The Touch Pad function allows the user to swipe a finger across the display and change the focus point.

Speaking of the electronic viewfinder, the A6500 includes an XGA OLED Tru-Finder. The high-contrast, high-resolution XGA OLED viewfinder is said to better reproduce darkness, color and fine details. It can be used with either 120 (100 in PAL region) or 60 (50) frames per second frame rates and has approximately 2.36-million dots. The 0.39"-type electronic viewfinder offers a 35mm equivalent magnification of 0.70x and 100% field coverage.
Besides the new internal features, addition of touchscreen functionality and an improved electronic viewfinder, you couldn't be faulted for not seeing much difference between the A6300 and A6500 bodies. On the back of the camera, the button layout is identical, save for a button becoming a C3 button instead of a C2 button. This change is due to Sony adding an additional C button on the top deck of the camera (which is otherwise unchanged in layout and functionality from the A6300). While the camera looks basically the same, the feel of it is stated to have been improved. The front grip is further recessed for improved comfort and the release button is larger. The feel of the mode and control dials and the rear face buttons has been enhanced and the viewfinder's eyepiece cup is now softer.

The A6500 still includes a built-in pop-up flash which has a guide number of 6 meters at ISO 100 (19.7 feet) and offers a claimed flash coverage of 16mm. Up to +/-3 EVs of flash compensation is available and you can utilize flash bracketing. The flash recycles in approximately 4 seconds. The camera has the same 1/160s x-sync as its predecessor, which is somewhat disappointing.
Sony A6500 uses same AF system found in the A6300 (and that's not a bad thing)
When the A6300 released this spring, we found its new 4D Focus autofocus system to be one of its strongest features, offering up a massive array of both phase detect and contrast detect autofocus points and great speed. The A6500 uses this same system which has 425 phase detection points and 169 contrast detect AF points. The hybrid AF system can acquire focus in as little as 0.05 second and has a sensitivity range of -1 to 20 EV.

To assist with continuous autofocus, the high-density focus system includes sophisticated tracking technology (which worked very well in the A6300). Additional focus features include Eye AF (which is compatible with AF-C), Lock-on AF (in which the camera automatically tracks a selected subject through the frame) and autofocus capabilities when using Focus Magnifier.
New menu interface is the user experience highlight with the A6500
Here at Imaging Resource, we have consistently remarked when reviewing Sony cameras that the menu system needed work. With the A6500 and its new menu interface, we hope that Sony has addressed our previous concerns. The refined user interface has a new categorization scheme, which displays group names and colored tabs. Without yet getting our hands on the camera, we cannot say for sure whether or not the menus are user friendly, but any improvement is welcomed. Also, regarding file naming, the A6500 allows for customized file names so you don't have to use the standard DSC prefix.

The A6500 utilizes a 1200-zone evaluative metering system and Exmor CMOS metering sensor. Its sensitivity is -2 to 20 EV and it offers evaluative, center-weighted and spot metering. You can link the metering spot location to the focus area when using flexible spot or expand flexible spot autofocus areas. There are two new metering modes: "highlight" and "entire screen average." The former meters exposure while focused on the brightest part of the frame and the latter maintains an average for the entire image.
Your standard assortment of shooting modes are all present (program, aperture priority, shutter speed priority and manual), but the A6500 also includes creative modes, such as sweep panorama and scene selection. The A6500 also has a silent shooting mode which allows for shooting at up to 3fps with full AF/AE tracking without the noise of faster continuous shooting modes, ideal for situations where silence is a necessity.
Remote control shooting has been improved as well. The Sony A6500 includes both Wi-Fi and NFC connectivity, so it is fully compatible with Sony's suite of PlayMemories Camera Apps, including Smart Remote Control, but you can also control the A6500 via a connected computer. You can control the camera's settings from the computer and even record images to both the camera and computer.

A6500 can shoot up to 307 consecutive frames at high speeds

The same improved LSI chip that contributes to improved high ISO image performance is also responsible for the A6500's vastly-expanded buffer depth. Naturally, how big the buffer depth is in the A6500 depends on image quality, but when you are shooting in the Hi Continuous drive mode and recording "fine" JPEG images, Sony claims that the A6500 can record up to 307 images over a duration of 35 seconds. The camera can shoot even faster than that, however, when recording in the Hi+ continuous shooting mode which provides 11fps shooting versus the 8fps shooting available in Hi. When shooting at 11fps, JPEG buffer depth decreases to 200 frames, which still eclipses the 47 Fine (44 Extra Fine) JPEG frames that the A6300 could consecutively capture. When recording RAW images, the A6500 is rated by Sony to capture up to 107 frames (100 when recording RAW + JPEG) when shooting in the Hi+ drive mode (11fps). We will have to test the camera's speeds for ourselves in the lab, but if the A6500 meets spec, this RAW buffer represents an over 80-frame improvement.

Sony A6500 includes same impressive 4K capabilities, adds Slow and Quick Motion mode
Like the A6300, the A6500 offers internal 4K recording. Shooting 3840 x 2160 resolution video in Super 35mm format -- which utilizes the image sensor's entire width -- the A6500 has full pixel readout capabilities and doesn't bin pixels. This results in the camera collecting 6K of information, thus oversampling it to produce 4K footage. 4K footage can be recorded up to 30 frames per second and 4K video is recorded at a 100 Mbps bit rate in the XAV S codec. Full HD video can be recorded at up to 120fps.
When recording 4K or Full HD video, users can select S-Log gamma recording which offers approximately 14 stops of exposure latitude in the S-Log3 setting. This is ideal for users who will be doing extensive post-production on video files as it provides expanded flexibility. The A6500's gamma display assist allows you to view video recording in S-Log gamma settings with more natural-looking contrast and exposure.

The new Slow and Quick mode supports both slow motion and quick motion. It does this by allowing selection of eight different frame rates ranging from 1 to 120fps. The end result is up to 60x quick motion and 5x slow motion video recording. The captured footage can be previewed right on your camera without the need to view it on a computer.
If you want to take full advantage of the camera's 4K video recording for still images, you can do that now too. The A6500 allows you to extract 8-megapixel stills from 4K video and 2-megapixel stills from Full HD video.
Sony A6500 battery life, ports and connections
The Sony A6500 uses the same rechargeable NP-FW50 lithium-ion battery pack as the A6300, which allows for up to 310 shots when using the electronic viewfinder and 350 shots when using the LCD monitor according to CIPA battery life figures. Unsurprisingly given the A6500's higher performance and built-in image stabilization, that's down from 350 and 400 shots per charge respectively for the A6300. Like the A6300, the Sony A6500 supports internal battery charging via USB.
Sony A6500 Review -- Product Image
Wired connectivity includes a Multi Micro USB 2.0 terminal, a Micro HDMI (Type-D) connector, Multi Interface hot shoe and a 3.5mm external mic jack (the A6500 includes a built-in stereo microphone). The Multi USB terminal also supports an optional RM-VPR1 wired remote control and tethered remote shooting from a Windows or Mac computer running Sony's Remote Camera Control utility. The A6500 doesn't include a headphone jack nor a vertical grip connector.
Also like the A6300, the A6500 records to Memory Stick Duo and SD memory cards and supports UHS-I, but not UHS-II, which is a bit surprising given the A6500's emphasis on continuous shooting performance. As mentioned above, the Sony A6500 includes Wi-Fi and NFC compatibility as well as QR functionality.

Comparing the Sony A6500 to the A6300

With the A6300 just released this past March, it might seem surprising that the A6500 has been announced in early October, but Sony says the A6300 will continue to be sold alongside the new model. While the two APS-C cameras look similar, there's no mistaking the A6500's place as the new flagship camera in Sony's mirrorless APS-C lineup. The sensor and autofocus systems are shared, but the vast increase in continuous shooting buffer makes the A6500 much more suited for high-speed shooting situations. Not only that, but the touchscreen functionality, enhanced electronic viewfinder, in-body image stabilization and redesigned menu system should make the A6500 a much friendlier camera to use and all of these improvements address issues we had with the otherwise excellent A6300 camera.

Initial thoughts on the Sony A6500

Speed and usability are the two main focuses of the A6500. The camera's new processing capabilities and touchscreen functionality are a testament to that. Add in all of the features it shares with the A6300 and you have a recipe for an excellent all-around APS-C mirrorless camera. The proof is in the pudding, however, so we will need to put the A6500 through its paces.
