SONY A9 Camera Body Black E-Mount 24mp Full Frame Stacked Sensor

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.

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. First¹ to use high-speed stacked design, its 24.2-megapixel² full-frame image sensor temporarily stores large-volume data in the integral memory for overall 20 times faster readout speed³. 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

Groundbreaking full-frame Exmor RS CMOS sensor and BIONZ X processor team up for 20fps continuous shooting⁴ with AF/AE tracking. Stunning high-speed performance and ample buffer let you capture the decisive moment.

Blackout-free shooting⁵

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.⁶

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 speeds up to 1/32000 sec.⁷

Electronic shutter speeds up to 1/32000 sec.⁷ 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.

No noise distraction

An anti-distortion⁸ electronic shutter allows silent shooting⁹ 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.

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.

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: Steadfast tracking

Reliable subject tracking in motion

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.

Eye AF for more precise focusing

Eye detection — enhanced by 30%¹⁰ 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-3¹¹ 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 shooting¹²with AF/AE tracking even when you use A-mount lenses¹³with a mount adapter (LA-EA3)¹⁴.

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 50-204800¹⁵ with minimum noise.

Technology for high-quality images

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 movies¹⁶

Full-pixel readout with no pixel binning makes it possible to condense approximately 2.4 times¹⁷ 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 120fps¹⁸ 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-stop¹⁹ 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

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.
