Bringing the speed Sony mirrorless shooters have been waiting for, 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. 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.
Matching its professional imaging capabilities is a well-rounded physical construction that is fully weather-sealed for use in trying environmental conditions. For clear, uncompromised viewing, a quad-VGA OLED Tru-Finder is featured with an impressive 3.686m-dot resolution and 120 fps refresh rate for clear, bright, and smooth eye-level viewing. Alternatively, a 3.0" 1.44m-dot tilting touchscreen LCD is also available to benefit working from high and low angles. Dual SD memory card slots, a customizable menu system, and a variety of physical control dials further round out the camera's intuitive design, and built-in Wi-Fi and Bluetooth enables wireless image sharing and remote camera control from linked mobile devices.
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.
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
