The Sony 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. Balancing the quickness of the processor is a well-matched 693-point phase-detection autofocus system that covers 93% of the image area for accurate and quick subject tracking in a variety of lighting conditions. Additionally, complementing both the imaging and focusing assets, the a9 also sports 5-axis SteadyShot INSIDE image stabilization to minimize the appearance of camera shake when shooting handheld.
24.2MP Full-Frame Exmor RS Stacked CMOS Sensor
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. The sensor's back-illuminated design also affords high sensitivity to an extended ISO 204,800 with reduced noise for clean image quality in a variety of lighting conditions. Additionally, uncompressed raw files can be recorded in 14-bit for greater color fidelity and post-production flexibility.
BIONZ X Image Processor
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. Continuous shooting up to 20 fps is supported for up to 362 consecutive JPEGs, or 241 raw frames, along with a top electronic shutter speed of 1/32,000 for freezing fast-moving subjects or working in bright lighting conditions. Benefitting the fast recording capabilities is an equally quick AF/AE metering system that functions at 60 times per second to continuously evaluate the scene in order to lock onto and track moving subjects. Additionally, due to the use of an electronic shutter, totally blackout-free monitoring is possible with the electronic viewfinder for more accurate compositions of moving subjects.
5-Axis SteadyShot INSIDE Image Stabilization
Packed into the robust a9 is a 5-stop effective 5-axis SteadyShot INSIDE image stabilization system that compensates for five different types of camera shake encountered during handheld shooting of stills and video. This allows users to confidently use any lens, even adapted lenses, for critical imaging without encountering blur from camera shake.
UHD 4K Video Recording in XAVC S Format
Internal recording of UHD 4K movies is possible in multiple frame rates up to 30 fps and, based on the Super35mm recording area and effective 20MP (6000 x 3376) resolution, 2.4x oversampling renders greater detail and full pixel readout is possible, that is void of pixel binning, for higher quality imagery with reduced moiré and aliasing. Full HD 1080p recording is also supported in frame rates up to 120 fps, and both resolutions utilize the 100 Mbps 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. In addition to high-resolution internal recording, uncompressed HDMI output also enables the use of an optional external recorder for clean 4K recording with 4:2:2 sampling.
Slow & Quick Motion
Take more control over your video capture capabilities with a variety of new frame rates available in an S&Q mode. This will allow shooters to capture Full HD video at one of either steps between 1-120 fps. These settings will allow you to slow down action as well as speed up a slow-moving scene. This setting is also NTSC/PAL switchable.
Enhanced Zebra Function
An enhanced Zebra function is ideally suited to aid in monitoring exposure values in high-contrast scenes. Video signal level targets can be set from 0 to 109, and specific ranges can be set to make exposure level adjustments easier.
Time Code and User Bit Settings
A time code can be used to record hours, minutes, seconds, frames on image data for more precise editing while the User Bit function can record date, time, and scene number to aid in editing together footage from multiple cameras.
693-Point Phase-Detection AF
Covering 93% of the image area, a focal-plane phase-detection autofocus system incorporates 693 points along with 25 contrast-detection areas for quick and precise focusing in in a variety of lighting conditions with sensitivity down to -3 EV. 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. The use of phase-detection points also enables the use of A-mount lenses via the optional LA-EA3 or LA-EA1 lens mount adapters with full continuous AF/AE tracking compatibility.
