Article:
It has been a good week for Sony. Just days after learning that they had risen from the world’s #3 to #2 camera maker, the Japanese electronics giant made the long-awaited blockbuster announcement of their new flagship camera, the groundbreaking Sony a9. Featuring the world’s first full-frame stacked CMOS sensor that delivers 24.2mp resolution, blackout-free continuous shooting at up to 20fps and 693 focal point phase detection AF points, the camera offers unprecedented performance for a pro-level camera.

The dawn of the true digital age
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.

Full-frame stacked CMOS sensor 

The combination of CMOS sensor and enhanced BIONZ X image-processing engine brings you true digital freedom.

High-speed continuous shooting

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

Blackout-free shooting

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.

AF/AE calculations up to 60 times/sec

Light directly reaches the image sensor without mechanical interruption. An ingenious fusion of mirrorless construction and new speed-enhancing technologies provides AF/AE at the full-frame focal plane.

Electronic shutter

Electronic shutter speeds up to 1/32000 sec. far surpass mechanical shutters for a new imaging expression. You can also maintain shallow depth of field without an ND filter, even under bright conditions.

Silence expands photographic potential

No noise distraction

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

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.

Stunningly wide coverage

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.

Fast AF speed

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.

Steadfast tracking

Uninterrupted AF and optimized AF algorithm dramatically enhance AF accuracy and tracking. Even during shutter release, constantly activated AF lets you continue tracking random subject motion.
More AF features for assured shooting
Eye AF for more precise focusing
Eye detection — enhanced by 30% 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-3 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 shooting with AF/AE tracking even when you use A-mount lenses with a mount adapter (LA-EA3).

New CMOS sensor

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 50-204800 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 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 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 movies
Full-pixel readout with no pixel binning makes it possible to condense approximately 2.4 times 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 3686k-dot electronic viewfinder (EVF) shows a clear image with fine detail. The ZEISS® T* Coating greatly reduces reflections. Smooth EVF images realized by 120fps frame rate even allow you to easily track a subject in fast motion.

5-axis image stabilization

New body-integrated 5-axis image stabilization unit offers a 5.0-stop shutter speed advantage. The live-view monitor image is also stabilized, so you can compose images easily even when shooting a fast-moving subject.

Battery stamina for professional use

A newly developed NP-FZ100 battery offers approximately twice 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 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

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.
