Sony Alpha a9 Mirrorless Digital Camera - E-Mount (Body Only)

The Sony Alpha a9 Mirrorless Digital Camera - E-Mount (Body Only) frees you from the limits of conventional SLRs that rely on mechanical systems. First to use high-speed stacked design, its 24.2-megapixel full-frame image sensor temporarily stores large-volume data in the integral memory for overall 20 times faster readout speed. The combination of CMOS sensor and enhanced BIONZ X image-processing engine brings you true digital freedom. 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.

NOTE: Body only; lenses and additional accessories sold separately.

High-Speed Continuous Shooting at up to 20fps

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

A 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/Second

Light reaches the image sensor directly 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 1/32,000 Sec.

Electronic shutter speeds up to 1/32,000 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(A mode 1/20,000 sec. f/8.0 ISO 1000).

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. The α9, however, has a vibration-free electronic shutter that can keep the camera stable, for razor-sharp images. 

Enhanced AF

More precise, virtually unfailing focus, swift reaction to fast motion, low-light reliability, and consistent tracking in continuous shooting.

Remarkable Number of Phase-Detection AF Points

The 693 AF phase-detection points on the surface of the image sensor cover approximately 93% of the image area. High-precision performance assures your focus on subjects.

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.

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% 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 shooting with AF/AE tracking even when you use A-mount lenses with a mount adapter (LA-EA3). 

Full-Frame 24.2 Megapixel Sensor

Sensitivity up to ISO 204,800 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 100-51,200, expandable to ISO 50-204,800 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.

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.

High-Resolution Quality of 4K Movies

Full-pixel readout with no pixel binning makes it possible to condense approximately 2.4x 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.
