New full-frame stacked CMOS sensor with integral memory
α9 is the mirrorless camera that delivers next-generation high-speed performance far exceeding SLRs. It’s equipped with the world’s first19 35mm stacked CMOS image sensor with integral memory for 20 times faster overall readout speed20. This 24.2MP21 image sensor achieves high sensitivity of up to ISO 204800 (extended)22 with the design of the back-illuminated structure.

20fps continuous shooting23 with AF/AE tracking
A combination of groundbreaking high-speed full-frame Exmor RS CMOS sensor and high-speed BIONZ X processor enables 20fps continuous shooting23 without a break for as many as 362 shots24. Thanks to the capability of displaying subjects nearly as naturally as they appear in reality, EVF lets you “sync” your intentions with camera behaviour.
High-speed BIONZ X image processing engine
Achieving processing speed beyond the previous model, BIONZ X image processing engine is optimised for speed to reliably capture fast-moving subjects and realise continuous shooting of up to 20fps23. Due to the newly developed image-processing algorithm, you can capture high-quality images with less noise all across the sensitivity range while maintaining natural details.
AF/AE calculations up to 60 times/sec
AF/AE is calculated up to 60 times per second27 and virtually uninterrupted not only while composing but also even releasing the shutter. You can depend on this continuous AF/AE — operated on the image sensor — to lock onto and track erratically moving subjects with significantly high speed, precision, and reliability.

Thanks to the non-mechanical electronic shutter system, you can observe the reality of what you’re shooting through the electronic viewfinder even during continuous shooting, without blackout interruption that typically occurs among optical viewfinders due to up-and-down mirror motion. Enhanced speed of the image sensor eliminates distracting EVF display lag in continuous shooting, so that you can compose images with natural comfort, like seeing scenes with your own eyes.

AI-based Real-time Tracking
Once the subject to be tracked has been specified, the precise focus is automatically maintained while the shutter button is half-pressed to provide framing flexibility and allow you to concentrate on composition. Changes in position are tracked with outstanding accuracy using a newly developed subject recognition algorithm.
High curtain speed of the electronic shutter suppresses rolling shutter effect29 and shows excellent performance in capturing moving subjects during sports and other fast-moving activities. (1) Conventional electronic shutter (2) α9 electronic shutter
A remarkable number of phase-detection and contrast-detection AF points
A total of 693 phase-detection points (covering approximately 93% of the image area) is now augmented by 425 contrast-detection AF points2 (expanded from 25), to ensure highly accurate subject detection even under poor lighting conditions, which is where contrast-detection AF is most effective.
Fast shutter release at 1/32000 sec.28, achieved silently
Explore the advantages of a high-speed silent shutter that is fully digital — without a physical mechanism. A result of Sony’s image sensor innovation, this shutter achieves speeds up to 1/32000 sec.28, beyond the limits of mechanical systems.
Precision AF effective down to EV-330 brightness
Low-light AF detection down to EV-330 at ISO 100 has been achieved. The precision AF system will function properly even when shooting dimly lit scenes. This opens dramatic new possibilities in low-light and night shooting.
Enhanced Real-time Eye AF2
A subject’s eyes can be detected as soon as the shutter is half-pressed or the AF-ON button is pressed, then tracked continuously2 in either AF-S or AF-C mode. In combination with Real-time Tracking, this further enhances the camera’s subject-tracking ability. There have also been improvements in AF response time when the custom assigned button is pressed, and it is now possible to select either the subject’s left eye or right eye.
Body-integrated 5-axis image stabilisation
The body-integrated image stabilisation system is fine-tuned to compensate accurately for 5-axis camera shake that can compromise handheld shooting. This gives you extremely high performance in both stills and movies, whether you’re shooting at longer focal lengths, in close-ups, or at night. Camera shake compensation is equivalent to using a 5.0-stop36 faster shutter speed, allowing stable determination of composition at times of capturing subjects in high-speed motion. Real-time effects can be monitored via live view.
