New dimension of photographic speed

A game-changing image sensor from Sony makes conventional camera mechanisms redundant, achieving speed and performance that are beyond the capabilities of mechanical devices. What's more, freedom from mechanical noise and vibration opens up a vast new world of imaging opportunities.


Driving force for full-electronic revolution

Innovative full-frame stacked CMOS sensor with integral memory

α9 liberates you from the limits of conventional SLRs that rely on mechanical systems. First2 to use high-speed stacked design, its 24.2-megapixel3 full-frame image sensor temporarily stores large-volume data in the integral memory for overall 20 times faster readout speed4. The combination of CMOS sensor and enhanced BIONZ X image-processing engine brings you true digital freedom.

High-speed continuous shooting at up to 20fps

High-speed continuous shooting at up to 20fps5

Groundbreaking full-frame Exmor RS CMOS sensor and BIONZ X processor team up for 20fps continuous shooting5 with AF/AE tracking. Stunning high-speed performance and ample buffer let you capture the decisive moment.

Blackout-free shooting

Blackout-free shooting6

Non-mechanical electronic shutter eliminates blackout with typical SLR mirror action. An uninterrupted view of the subject is available even during shutter release, with 60fps live-view capability and minimal display lag in continuous shooting.

Silence expands photographic potential

No noise distraction

No noise distraction

An anti-distortion9 electronic shutter allows silent shooting10 without mechanical mirror and shutter noise. It’s ideal for sports and subjects that demand quiet operation, greatly expanding camera versatility

No unwanted vibration

No unwanted vibration

During SLR shooting, mirror shock and shutter release shock cause subtle vibration. α9, however, has a vibration-free electronic shutter that can keep the camera stable, for razor-sharp images.

Mobility leads to unprecedented opportunities

Professional features and performance in a compact body. The freedom of mobility inspires fresh creativity.


Swift, accurate, and reliable AF

Discover enhanced AF — more precise, virtually unfailing focus, swift reaction to fast motion, low-light reliability, and consistent tracking in continuous shooting.

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.

More AF features for assured shooting

Eye AF for more precise focusing

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

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

A-mount lens AF support

Focal-plane phase-detection AF system with 693 AF points functions reliably. Enjoy up to 10fps continuous shooting13with AF/AE tracking even when you use A-mount lenses14with a mount adapter (LA-EA3)15.

Outstanding image quality

Full-frame 24.2-megapixel3 sensor with sensitivity up to ISO 20480016 and wide dynamic range captures outstanding image quality.


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.

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.

14-bit RAW

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.


Efficient workflow and professional reliability

In addition to a magnesium alloy body that assures the camera’s all-around toughness and reliability, largely amplified versatile features enhance operability, supporting severe usage in professional photography.


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.


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


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.

Dual slots

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.

FTP file transfer

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

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.
