What only a9 can do
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. a9 provides continuous tracking of moving subjects for foolproof AF/AE while traditional SLRs can only challenge such AF/AE performance improvements. Moreover, a9 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 expectations with a9.
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
a9 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.
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.
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.
Swift, accurate, and reliable AF
Discover enhanced AF - more precise, virtually unfailing focus, swift reaction to fast motion, low-light reliability, and consistent tracking in continuous shooting.
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.
Body-integrated 5-axis image stabilization
The body-integrated image stabilization 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-stop faster shutter speed, allowing stable determination of composition at times of capturing subjects in high-speed motion.
One-touch remote & One-touch sharing
Use one-touch remote to turn a smartphone or tablet into a viewfinder/remote control. One-touch sharing transfers photos/videos to your device for social network site (SNS) sharing. Just install a PlayMemories Mobile app via Wi-Fi to your NFC-enabled Android device, and then touch the device to the camera to connect them. If you don't have NFC, use QR code compatibility to pair the devices.
