The A9 Mirrorless Camera takes impressive multimedia capabilities and ups the processing capabilities for ultra-fast continuous shooting. The a9 features a first-for-full-frame 24.2MP Exmor RS stacked CMOS that affords impressively quick readout speeds to benefit from up to 20 fps continuous shooting and UHD 4K video recording. The sensor's back-illuminated design also affords high sensitivity to an extended ISO of 204,800 with reduced noise for clean image quality in a variety of lighting conditions. 

Continuous shooting up to 20 fps is supported for up to 362 consecutive JPEGs or 241 raw frames. Totally blackout-free monitoring is possible with the electronic viewfinder for more accurate compositions of moving subjects. The density of focusing points from this hybrid AF system also enables High-density Tracking AF Technology, which is adept at tracking moving subjects in a variety of lighting conditions. Expand Flexible Spot employs neighboring focus points to retain focus on moving subjects even if the originally selected point loses focus. The Focus Magnifier function can be used for critical focus when homing in on minute subject details. This allows users to confidently use any lens, even adapted lenses, for critical imaging without encountering blur from camera shake. 

Macro and high-magnification imagery, on the other hand, will benefit from the inclusion of horizontal and vertical shift compensation. All shooting styles will get usage out of the roll compensation. All 5 axes of stabilization will function at all times, even when used with third-party lenses and adapters or lenses with built-in optical stabilization. Full HD 1080p recording is also supported in frame rates up to 120 fps, and both 4K and FHD resolutions utilize the 100 Mb/s XAVC S format contained within an MP4 wrapper with 4:2:0 sampling. The high-speed, 120 fps recording also enables 4x and 5x slow-motion movie recording with the frame rate set to either 30p or 24p. The EVF also sports a ZEISS T* anti-reflective coating to reduce reflections and a high 120 fps refresh rate can be used to reduce lag for a smoother viewing experience.

Additionally, a fluorine coating has been applied to the outermost viewfinder element to benefit cleaning. Magnesium-alloy body design is both lightweight and durable, and also weather-sealed for use in trying environmental conditions. Built-in Wi-Fi enables the a9 to instantly share imagery to mobile devices for direct sharing online to social networking, via email, and to cloud storage sites.
