The Alpha a9 Mirrorless Digital Camera takes impressive multimedia capabilities and ups the processing capabilities for ultra-fast continuous shooting. Making use of a 24.2MP full-frame Exmor RS stacked CMOS sensor and BIONZ X image processor, the a9 is capable of shooting at up to 20 fps, recording UHD 4K video internally, and shooting with an expanded sensitivity range to ISO 204,800.Matching its professional imaging capabilities is a well-rounded physical construction that is fully weather-sealed for use in trying environmental conditions.
Poised for speed, the a9 features a first-for-full-frame 24.2MP Exmor RS stacked CMOS that affords impressively quick readout speeds to benefit up to 20 fps continuous shooting and UHD 4K video recording.
Working in conjunction with the stacked CMOS sensor is an apt BIONZ X image processor that ensures quick processing speeds to keep up with fast-paced shooting applications.

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. First2 to use high-speed stacked design, its 24.2-megapixel3 full-frame image sensor temporarily stores large-volume data in the integral memory for overall 20 times faster readout speed4. 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 shooting5 with AF/AE tracking. Stunning high-speed performance and ample buffer let you capture the decisive moment.
Blackout-free shooting6
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. (A) Blackout-free shooting (B) Shooting with blackout
AF/AE calculations up to 60 times/sec.7
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. (1) AF/AE calculations (2) 60times/sec (3) 20 frames/sec
Electronic shutter speeds up to 1/32000 sec.8
Electronic shutter speeds up to 1/32000 sec.8 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 1/20000 sec. F8.0 ISO 1000)
No noise distraction
An anti-distortion9 electronic shutter allows silent shooting10 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.
