A 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.
Innovative full-frame stacked CMOS sensor with integral memory
α9 liberates 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.

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
Note: This camera is equipped with electronic and mechanical shutters.
The features described in this section are primarily related to electronic shutter operation.
Professional features and performance in a compact body. The freedom of mobility inspires fresh creativity.
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.
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
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.
