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 first 35 mm stacked CMOS image sensor with integral memory for 20 times faster overall readout speed. This 24.2 MP image sensor achieves high sensitivity of up to ISO 204800 (extended) with the design of back-illuminated structure.

High-speed BIONZ X image processing engine
The camera's image-processing algorithms have been upgraded with the latest software update, allowing higher levels of natural tonal gradations and more stable AWB for continuous shooting.

20fps continuous shooting 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 shooting without a break for as many as 362 shots. Thanks to the capability of displaying subjects nearly as naturally as they appear in reality, EVF lets you “sync” your intentions with camera behavior.

AI-based Real-time Tracking
Once the subject to be tracked has been specified, 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.

Blackout-free shooting
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.

AF/AE calculations up to 60 times/sec.
AF/AE is calculated up to 60 times per second and is virtually uninterrupted, both while composing the image and even upon 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.
