What only α9 can do
This mechanism-free camera can deliver a-class-above performance conventional mechanical SLRs have only sought. For example, this system realizes a totally blackout-free viewfinder while conventional systems can only try to reduce blackout time. A high-speed, vibration-free, silent Anti-Distortion shutter vastly extends the range of shooting situations while a mechanical system can only aim for lower vibration and quieter shutter release sound. α9 provides continuous tracking of moving subjects for foolproof AF/AE while traditional SLRs can only challenge such AF/AE performance improvements. Moreover, α9 allows its viewfinder to show not only images of the subject — available on conventional systems — but also the final image of a shot. Now, thanks to a new image sensor that superbly manages all these roles, you can surpass all expectation with α9.
Note: This camera is equipped with electronic and mechanical shutters. The features described in this section are primarily related to electronic shutter operation.
4D FOCUS: Fast AF speed
Fast Hybrid AF achieves rapid AF for full-frame photos
Capture fast-moving subjects with reliable rapid AF. The speed and accuracy of this Fast Hybrid AF System are further improved in combination with the enhanced BIONZ X image processing engine.
4D FOCUS: Stunningly wide coverage
693. Remarkable number of phase-detection AF points
The phase-detection points on the surface of an image sensor — 693 AF points — covers approximately 93% of the image area. High-precision performance assures your focus on subjects.
Eye AF for more precise focusing
Eye detection — enhanced by 30%11 through improved face detection — keeps the subject’s eye in focus, even if the face is turned at an angle or partially shaded. Wide focal-plane phase-detection AF sensor shows its ability in challenging shots.Reliable even in low light
Capture subjects with high AF precision down to light levels as low as EV-312 at ISO 100, due to the high sensitivity image sensor.A-mount lens AF support
Focal-plane phase-detection AF system with 693 AF points functions reliably. Enjoy up to 10fps continuous shooting13 with AF/AE tracking even when you use A-mount lenses14 with a mount adapter (LA-EA3)15.New CMOS sensor for imaging excellence
High sensitivity, a back-illuminated configuration, gapless on-chip lens architecture, and other Sony innovations deliver stunning images in a wide range of photographic situations. Standard ISO range is ISO 100-51200, expandable to ISO 50-20480016 with minimum noise.
Technology for high-quality images
Utilize high-quality imaging that unites all available image sensor technologies — including back-illuminated structure, gapless on-chip lens architecture.

5-axis image stabilization
New body-integrated 5-axis image stabilization unit offers a 5.0-stop20 shutter speed advantage. The live-view monitor image is also stabilized, so you can compose images easily even when shooting a fast-moving subject. (1) Yaw (2) Pitch (3) Roll
BIONZ X enhanced speed image processor
Enhanced image processing combined with new front-end LSI reduces noise while improving detail depiction over a wide sensitivity range. Improved detail rendering enables lifelike texture reproduction.
Uncompressed 14-bit RAW
Uncompressed 14-bit RAW format is supported, and it or the current compressed RAW format can be selected as required. Uncompressed 14-bit RAW is a good choice in situations where the sensor's wide dynamic range and fine gradation reproduction will benefit the images being captured.

Beautiful 4K imaging
High-resolution quality of 4K movies17
Full-pixel readout with no pixel binning makes it possible to condense approximately 2.4 times18 the amount of data required for 4K (the equivalent of the amount of data required for 6K) into 3840 x 2160 4K output. This oversampling process plus full-frame pixel readout without binning results in the highest possible 4K movie image quality.
Quad-VGA OLED Tru-Finder™
The new high-resolution 3686k-dot electronic viewfinder (EVF) shows a clear image with fine detail. The legendary ZEISS® T* Coating greatly reduces reflections. Smooth EVF images realized by 120fps19 frame rate even allow you to easily track a subject in fast motion. Fluorine coating on the outermost lens provides improved protection from dirt.
Dual media slots
Use two slots — one for SD and one for SD/Memory Stick cards — to simultaneously backup still/movie data, save RAW/JPEG images to different cards, and copy between cards. Lower card slot supporting UHS-II type cards is available for fast transfer speed.
Battery stamina for professional use
A newly developed NP-FZ100 battery offers approximately twice11 the life of the previous NP-FW50. Capture up to approx. 480 still frames on one charge — and further increase the number of shots with an attached optional vertical grip (sold separately) that can hold two batteries.
FTP file transfer
A new terminal for wired LAN connection lets you transfer still images to an FTP server for viewing and management. Since FTPS (File Transfer Protocol over SSL/TLS) is supported, image files can be encrypted while being transferred.
My Menu & new menu interface
A new My Menu feature lets you register up to 30 menu items for instant recall, arrange items in any order, and erase unused items. Also, primary menus have been reorganized for smoother search and operation.
Footnotes
2 The world’s first as 35mm full-frame stacked CMOS image sensor with integral memory, as of April 2017, based on Sony research.
3 Approximate effective pixels
4 Compared with the front-illuminated CMOS image sensor in the α7 II.
5 “Hi” continuous shooting mode. At shutter speeds higher than 1/125 sec. In AF-C mode the maximum continuous frame rate will depend on the shooting mode and lens used. A software update may be required for some lenses. Visit Sony’s support web page for lens compatibility information.
6 Electronic shutter mode. Focus will not track the subject at apertures smaller than F11 (F-numbers higher than F11). The focus point will be fixed at the first frame. Display updating will be slower at slow shutter speeds.
7 At shutter speeds higher than 1/125 sec. The number of AF calculations will depend on camera settings and the lens used.
8 Selectable only in S and M modes.
9 Slight distortion may occur in some shooting conditions.
10 Silent shooting is possible when Shutter Type is set to 'Electronic' and Audio is set to 'Off'.
