Camera body

Styling and controls: Designed for improved usability

While the Sony A9 shares similar design elements with the Sony A7 series of cameras, it has a few differences that should satisfy Sony shooters. On the top deck of the camera, one of these changes are stacked, independent Drive and Focus Mode dials. No longer will you need to scroll through menus or set a custom function for switching the focus mode. Both dials are lockable as well to prevent accidental changes to settings during shooting.

The back of the camera has seen changes as well. There is now a dedicated AF-On button, perfect for photographers who enjoy using back-button autofocus techniques. Below the AF-On button and to the right of the display more on that in a bit is a new multi-selector joystick. This multi-selector provides direct, immediate control over autofocus points or for scrolling through images during playback. Astute readers will also note that the video record button has been moved next to the EVF, which puts it within natural reach of your thumb.

The Sony A9 includes numerous ease-of-use changes as well, some of which may not be immediately apparent but will help make the camera more user-friendly. There is a new My Menu feature. This dedicated menu allows users to store and customize up to 30 menu items for quick recall. You can also designate certain settings, such as shutter speed, aperture, AF area and more, to be recalled when holding function buttons. Regarding focus settings in particular, you can register frequently used focus area settings for future use and can use separate or identical focus areas and points for horizontal or vertical-orientation shooting. Customizability matters for many users and in total, there are 11 buttons on the A9 which can be customized and reassigned to control up to 72 different functions.

Durable and pro-oriented body is rugged and offers new workflow features

Designed to meet the exacting standards of professionals, the Sony A9 includes numerous reliability and usability improvements over the A7 series of cameras. The magnesium alloy body has dust and moisture resistance around most of its controls and buttons, allowing the camera to be used in demanding situations, although note that it is not guaranteed to be 100 percent dust and moisture proof despite its seals and tongue-and-groove joints. The A9 will be able to be used longer as well, as the new NP-FZ100 battery provides twice the life of the previous NP-FW50 battery, offering approximately 480 still frames on a single charge when using the electronic viewfinder, and 650 shots with the LCD monitor. There will also be an optional vertical battery grip available which can double battery life. There will also be a NPA-MQZ1K Multi Battery Adaptor Kit which can hold up to four batteries and act as external power source.

Looking at the side of the camera, we find dual media slots. The Sony A9 uses SD cards but one of its slots can also use a Memory Stick Duo card. Unlike previous Sony cameras, the Sony A9 now features UHS-II card support. It will be interesting to see how the buffer clearing performance improves with the UHS-II support compared to prior Sony cameras. Note that the second memory card slot only supports up to UHS-I.

There have also been changes to the E-mount itself. Sony has increased the rigidity of the mount and added a pair of screws (bringing the total to six) so that the mount will remain durable and strong when supporting heavy telephoto lenses.

Workflow is critical for photographers on strict deadlines, so Sony has included wired LAN support for FTP file transfer. Further workflow improvements include new PC remote storage options, faster startup, copyright information embedding, a flash sync terminal, the ability to have the camera automatically shut off at certain temperatures and the ability to edit the first three characters of file names.

The Sony A9 also includes wireless via Wi-Fi, NFC and Bluetooth functionality. In addition to being able to remotely control the camera and transfer images wirelessly with PlayMemories Mobile on your smartphone, the camera can also embed location data from your phone into captured images.

Image stabilization

With a newly-developed 5-axis optical image stabilization unit built into the body, the Sony A9 is stated to offer up to five stops of vibration reduction. And since stabilization is applied to the live view image, it helps keep your shots properly composed even when shooting in low light or using a long, heavy lens.

Display: First tilting touchscreen display in a flagship Sony camera

The Sony A9 includes a 3-inch type 1,440K-dot touchscreen LCD. This is the first pro-oriented Sony camera to include a touchscreen display and allows functionality such as Touch AF. The monitor tilts as well, a maximum of 107° upward and a maximum of 41° downward. The display includes WhiteMagic technology (white pixels in addition to red, green and blue) designed to help the display be viewable even when used in bright lighting conditions.

Viewfinder and shutter: No blackout and vibration-free, silent shooting

The Sony A9 is all about speed. Being able to capture images quickly doesn't mean much to sports shooters in particular if you don't have a good viewfinder experience. We have seen Sony give attention to viewfinder speed and performance in many of its recent cameras, but the A9 aims to take it to the next level with zero viewfinder blackout, even when shooting at 20 frames per second, and a direct viewfinder image of the subject during tracking and capture.

Looking at the viewfinder itself, it is a 0.5-inch OLED viewfinder with 3,686K dots and it operates with a 120fps refresh rate (60fps live-view refresh rate). The Tru-Finder EVF features 0.78x magnification and 100% coverage. The viewfinder also has Zeiss T* coating to reduce reflections.

Paired with the viewfinder is a hybrid shutter mechanism. The mechanical shutter has been refined and offers lower vibration than previous mechanical shutters. Further, the shutter is rated for 500,000 cycles. The silent, zero-vibration electronic shutter offers shutter speeds up to 1/32,000s and is said to offer minimal distortion. The mechanical shutter tops out at 1/8,000s, but both can shoot with shutter speeds as slow as 30 seconds. The mechanical shutter also offers a bulb setting. Further, flash sync speed is 1/250s.

Sony A9 Shooting Features

Image sensor: 24.2-megapixel sensor is the first-ever stacked full-frame CMOS image sensor

The Sony A9 is the first full-frame camera to utilize a Sony Exmor RS back-illuminated image sensor with a stacked structure. This stacked design is engineered to offer faster readout. In fact, Sony states that the new sensor is 20 times faster than their previous front-illuminated CMOS image sensor found in the A7 II. The pixel layer of the image sensor sits on top of a separate pixel layer – which has a high-speed signal processing circuit and integral memory – which both sit above the Bionz X image processing engine, which itself includes a new front-end LSI to reduce noise while improving image detail over a wider ISO range.

Sony A9 Review -- Product Image

The 24.2-megapixel Exmor RS CMOS sensor can capture uncompressed or compressed 14-bit RAW images across a wide ISO range of 50 to 204,800, although the native ISO range is 100 to 51,200. Sony is claiming 14-stop dynamic range from the new sensor. Further, the sensor includes a charge protection coating on its optical filter and an image sensor shift mechanism to help keep dust off the sensor.

Exposure: Improvements to metering and Auto ISO

With a 1200-zone evaluative metering sensor, the Exmor RS CMOS sensor-based metering system of the Sony A9 has a working range of -3 EV to 20 EV. The metering modes include Multi-segment, Center-weighted, Spot (standard and large options are available), Entire Screen Average and Highlight. Exposure compensation is available for +/-5 EV in 1/3 and 1/2 EV steps. Users can also set a standard exposure value of +/-1 EV in 1/6 stop increments which can be set independently for each metering mode.

Regarding spot metering, the A9 can link either a standard or large spot metering area to flexible or expanded spot focus areas. The highlight metering mode helps prevent blown highlights by detecting the brightest area in the frame and the average mode is designed to provide consistent exposure even when changing composition.

The Sony A9 offers more customization to Auto ISO. You can set the shutter speed above which the ISO changes when the camera is set to P or A shooting modes. You can specify a low ISO Auto limit for minimizing motion blur when shooting a moving subject as well.

Autofocus: 693 phase-detection autofocus points over 93% of the image area

The Sony A9 uses Sony's latest hybrid 4D Focus autofocus system. This autofocus system includes 693 phase-detection points which cover 93% of the image area. In addition to these 693 PDAF points, there are also 25 contrast-detection autofocus points. The end result is a hybrid autofocus system which Sony claims is 25% faster than the autofocus system in the Sony A7R II.

Autofocus isn't solely about speed, however, as accuracy, low-light performance and modes matter too. The Sony A9 includes enhanced Eye AF, providing approximately 30 percent better eye accuracy compared to the Sony A7 II. Face detection has seen improvement. Low light autofocus is rated down to -3 EV, which while not rated for as low light as some professional DSLR cameras, is still very low. The A9 offers an expand flexible spot mode, designed for moving subjects, which can automatically shift focus to one of eight adjacent autofocus points when tracking a subject.

For users with A-mount lenses, it is worth pointing out that the A9 is designed to work well with adapted A-mount lenses as well. Granted, continuous autofocus tops out at 10 frames per second with A-mount lenses mounted, but that should still prove plenty fast for many users.

Sony A9 Review -- Product Image

Photographers looking for extra reach and using the A9 in APS-C mode (either with a full-frame lens or an APS-C lens) will still be able to utilize many autofocus points. When shooting with a full-frame lens in the APS-C format (10 megapixels), the A9 can use 299 phase-detection autofocus points. When using an APS-C lens, the number drops to 221 PDAF points and 25 contrast-detect AF points.

Performance: Capture up to 241 full-resolution RAW images at 20 frames per second

Speed. That is clearly the primary focus for Sony with the A9 and its specifications certainly look promising. The camera can capture up to 241 full-resolution compressed RAW images (or 362 max-quality JPEG images) at a blazing fast 20 frames per second. Not only that, but the camera is doing this with full AF/AE tracking and without viewfinder blackout. The A9 calculates AF and AE up to 60 times per second, allowing what Sony says is improved tracking of subject movement and changes in lighting conditions.

If you want to shoot RAW+JPEG or uncompressed RAW, Sony’s published specifications claim 222 RAW+JPEG frames, 128 uncompressed RAW frames and 118 uncompressed RAW+JPEG image buffer depths. As always, we will need to test the camera in our lab to determine its real-world performance and its buffer clearing speeds, but the A9's improved readout speeds and UHS-II support look poised to offer solid performance gains over prior Sony cameras.

Sony A9 Video: 4K UHD video at 100Mbps

The Sony A9 records 4K UHD (3840 x 2160 resolution) video with full pixel readout and no pixel pinning. This allows the camera to condense up to 2.4 times the necessary data for 4K video into a 4K output. The camera offers clean HDMI output for both 4K and Full HD video to external recorders or monitors and the camera can simultaneously record internally and externally.

4K video can be recorded with a bit-rate up to 100Mbps and frame rate as fast as 30 frames per second in the X AVC 4K file format. Full HD video can be recorded at up to 120fps using the XAVC S HD recording format with a 100Mbps bit-rate. Regarding frame rate, the A9 records video from 1 frame per second up to 120fps in Full HD quality, allowing recording of 60x quick motion to 5x slow motion video. Slow and Quick motion effects can be previewed in camera, eschewing the need for post production.

Autofocus performance is said to be improved for video recording thanks to the new hybrid 4D Focus system. There is now a wider AF area that covers the same amount of the frame as still images and focus tracking is said to be better as well.

Sony A9 Pricing and Availability

The Sony A9 will be available starting May 25th with a price tag of about US$4,500 (CAD$6,000).

Alongside the camera, Sony introduced a variety of accessories for the Sony A9. In addition to the new NP-FZ100 battery and vertical grip and multi-battery adaptor kit mentioned earlier, Sony is releasing a GP-X1EM Grip Extension, FDA-EP18 Eyepiece Cup with locking mechanism and a shatterproof PCK-LG1 glass screen protector for the new touchscreen display.

Our take on the Sony A9: Sony puts Canon and Nikons flagship DSLRs in its crosshairs

It's clear that Sony is aiming to bring photographers over from the venerable flagship DSLR cameras from Canon and Nikon. The A9 is not a replacement for the Sony A7 series of cameras, but is rather a new line designed to offer demanding professionals shooting speeds matching or exceeding its DSLR competition while providing state-of-the-art autofocus performance in a smaller camera body.

We need to evaluate the Sony A9 in real-world shooting situations to see how it compares to cameras such as the Canon 1DX Mark II and Nikon D5, but the Sony A9 is clearly trying to make its mark in that camera class, both in terms of its feature set and its price tag. It will be very interesting to see how it stacks up, but what we have seen so far is promising.

Hands-on with the Sony A9

A true mirrorless monster

Sony A9 Review - Hands On
The Sony A9 with FE 100-400mm f/4.5-5.6 GM OSS lens & battery grip.

After the press conference of Sony's surprise unveiling of their latest flagship Alpha camera, the Sony A9, I was able to get some brief hands-on time with the new camera. With various units set up around a few indoor sporting demonstrations, I was able to get a sense of just how fast and nimble this new full-frame mirrorless camera really is. Unfortunately, these demo cameras had taped-up card slots, so no sharing of any photos taken with the camera today. (But stay tuned!)

The Sony A9 is all about speed and performance

First and foremost, this camera is all about speed and performance. Thanks to its stacked sensor design, the A9 can shoot at up to 20 frames per second for over 200 frames in RAW or RAW+JPEG mode. The stacked sensor design, first seen in the 1-inch-type RX100 IV, sees the A9 now brings that tech up to full-frame. The on-board memory and signal processing handles the massive data load extremely quickly, giving you that nimble high-speed burst capability. In my brief experience with the camera thus far, let me tell you that it is indeed fast. Very fast. In a sports-shooting scenario, you can fire off bursts of shots in quick succession, or mash the shutter button for tons of frames to make sure you nail the precise moment.

Sony A9 Review - Hands On

After firing off a big burst of shots, the camera, of course, immediately begins processing and writing images to your memory card, or cards. As I've experienced before with Sony cameras, certain operations, like trying to access the menu, while the camera is writing to the card are unavailable, which is a little frustrating. The inclusion of a UHS-II card slot speeds things up dramatically in this regard, so you'll spend less time locked out of the camera. I do wish that the A9 had two UHS-II slots, but alas one slot is still UHS-I. But, hey, two card slots are better than one, so I'll take it.

It should be noted that the 20fps burst rate is available for electronic shutter only. Switching to mechanical shutter mode, the burst drops down dramatically, to just 5fps at the fastest.

Coupled with its impressive continuous shooting capabilities is the A9's super-fast hybrid autofocus system. Sporting a whopping 693 phase-detection AF points, the A9's autofocus coverage is practically the entire sensor. My initial impression is that AF performance is very good. The camera was quick and decisive to both acquire and adjust focus, and it seemed to track moving subjects very quickly. Of course, not being able to see the images on my computer, it's hard to know if the camera nailed every shot in a burst sequence, but my take is that it performed very well. Needless to say, I can't wait to try it out in the field with some tricky sports, especially difficult indoor sports like basketball.

The lack of viewfinder blackout is awesome

The new EVF on the A9 is also fantastic. The A7R II, which I had by my side, already has a great-looking EVF, but the one on the A9 has an even higher resolution 3686k-dot screen, making for an even better user experience. One of the big features about the Sony A9 is the blackout-free shooting experience. In both the EVF, and on the LCD, the camera does not blackout between frames when continuously shooting with the electronic shutter.

In normal single-shot or mechanical shutter shooting modes, the EVF's refresh rate is set at 120fps, making it easy to follow moving subjects. When using the blackout-free electronic shutter-based continuous shooting mode, the viewfinder frame rate is pegged at 60 fps. That's still plenty fast, and given the cool blackout-free operation, it feels very easy and very responsive to follow and track fast-moving subjects, as well as not miss decisive moments.

The A9 is super-quiet when using the electronic shutter

Sony made a big point about how quiet the A9 is, especially highlighting Silent Shooting mode, which has been included in a number of previous Alpha mirrorless cameras, such as the A7S II and A7R II, for example. This mode, using the electronic shutter, makes shooting completely silent, which is great for photojournalist and other documentary photography work as well as wildlife photographers; key demographics for the Sony A9. But, even when not using Silent Shooting mode, the electronic shutter operation on the A9 is incredibly quiet. Now, if you switch to the mechanical shutter, then yes, you hear noticeable "ka-chunk" sounds when you fire off a shot. Given the performance advantages on the A9 when using the electronic shutter, I'd be hard-pressed to opt for the mechanical one.

Familiar A7-style body, but with nice improvements

Design-wise, the Sony A9 looks quite similar to its A7-series brethren, but there are a handful of thoughtful new additions to the A9's body design. For starters, there's now a second top-deck dial on the left side of the EVF. This dual-layer dial has a locking top dial for drive mode settings, while the bottom layer controls focusing modes. The bottom dial here is very reminiscent of the drive mode on a number of Nikon DSLRs; there's an unlock button that you press and hold with your thumb while your index finger rotates the dial via a small tab. This secondary dial is quite handy overall, as it provides a fast, physical adjustment to two very important and highly-used settings. You spend less time diving into menus and more time shooting.

Sony A9 Review - Hands On

Another new addition to the camera's controls is the introduction of a joystick control on the rear of the camera, taking the place of the AF/MF/AEL switch lever seen on the A7-series models (since focus mode is now up in that top-deck dial). The rather large and flat joystick control works very well to make on-the-fly focus point changes when using AF modes like Flexible Spot. The joystick control is responsive and solid, while at the same time not feeling flimsy or fiddly. In other words, I didn't feel as though I'd accidentally press it or make incorrect adjustments.

Sony A9 Review - Hands On

In addition to the joystick control, the A9 also gains a dedicated AF-ON button, which is super helpful for those who use back-button focusing. There's also a dedicated auto-exposure lock button off to the right as well.

The rest of the controls feel very similar to those on the Mark II series of A7 models, so if you're already familiar with the Sony A7, the A9 is a no brainier to pick up and use. Comfort-wise the A9 feels great in the hand and, again, very similar to the A7-series. Dials and controls feel sturdy and the grippy material around the handgrip provides a solid hold. Given its compact nature, I do find that my pinky finger doesn't quite fit on the grip when hold the camera; I often myself wrapping my little finger underneath the base of the camera. I find myself doing this with a gripless E-M1 Mark II, for example, as well. If I were shooting longer, heavier glass, such as an adapted Sony A-mount telephoto lens or even the 70-200mm f/2.8 G Master lens, I'd prefer the camera to be bit "taller" or simply resort to a battery grip. And given the new battery grip design for the A9, with space for a second battery, that seems like a win-win; more comfort and much longer battery life.

Sony A9 Hands-On: Battery Life

Lastly, the Sony A9 is the first full-frame Sony mirrorless model to offer touchscreen functionality. (Finally!) The implementation is fairly limited, but arguably put to use for the most appropriate function: touch-to-focus -- simply tap the screen where you want the AF point, or you can tap and drag your finger around the screen to move the AF point. You can'€™t, however, navigate menus or interacting with on-screen displays.

Hands-on with the new 100-400mm GM lens

And speaking of longer lenses, I also had some hands-on time with the new FE 100-400mm f/4.5-5.6 GM OSS lens. For such a versatile telephoto range, the new Sony 100-400mm GM lens is incredible compact. In fact, from a distance, I often got it confused with the Sony 70-200mm f/2.8 GM lens; it's that compact. Compared to other 100-400mm lenses for full-frame DSLRs, the Sony 100-400mm GM lens is indeed very compact and lightweight. On a non-gripped A9 body, it balances decently well, but I'd personally enjoy using a grip when this lens is attached.

Sony A9 Review - Hands On

Like the 70-200mm GM lens, the new 100-400mm sports a similar overall design, complete with a stylish white paint job. The zoom and focus rings feel very smooth. The zoom ring has adjustable tension, letting you personalize how light or stiff the zoom action is. In the full "loose" position, the zoom ring was very smooth and easy to rotate, but if you hold the lens downward it can extend on its own a bit (a.k.a. "lens creep") so make sure and either lock the zoom or adjust the tension accordingly depending on how you'll be using and carrying it.

Sony A9 Review - Hands On


Overall, the Sony A9 looks to be a total beast of a camera. Performance-wise, the camera is just amazingly fast, at least from my initial impressions. With the A9, Sony has taken aim at the flagship DSLRs like the Canon 1D X Mark II and Nikon D5. The Sony A9 takes what made the A7-series great, such as their excellent image quality and compact design, and kick things up a notch, a big notch, to bring the performance and speed aspects needed by professional sports, wildlife and press photographers.
