The Sony Alpha a9 Mirrorless Digital Camera has impressive multimedia capabilities and increases 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 Sony Alpha a9 Mirrorless Digital Camera 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 Stabilisation to minimise 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 enable 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 Full-Frame Exmor RS Stacked CMOS Sensor 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 colour 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 compatibility.

The apt focus system also lends itself to a variety of focusing functions for refined accuracy, including Lock-on AF, which maintains focus on moving subjects throughout the use of a configurable frame that is set over the desired moving subject, and Expand Flexible Spot, which employs neighboring focus points to retain focus on moving subjects even if the originally selected point loses focus.

Additionally, Eye AF can be used to base focus on recognized subjects’ eyes for portraits and is available in both AF-S and AF-C modes. Autofocus can also be used in conjunction with the Focus Magnifier function for critical focus when homing in on minute subject details.

In addition to autofocus, the a9 also features a Peaking MF function to benefit manual focus control by highlighting sharp edges of contrast for a more objective means of acquiring sharp focus.

5-Axis SteadyShot INSIDE Image Stabilisation

Packed into the robust a9 is a 5-stop effective 5-Axis SteadyShot INSIDE Image Stabilisation 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.

For long focal lengths, the system will correct for pitch and yaw adjustments. 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 stabilisation.

UHD 4K Video Recording in XAVC S Format

Internal recording of UHD 4K movies is possible at 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, void of pixel binning, for higher quality imagery with reduced Moiré and aliasing.

Full HD 1080p recording is also supported at 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.

4K video recording also has the ability to produce 8MP stills during playback by taking a frame grab from a movie and storing it as a separate file.

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 & User Bit Settings

A Time Code can be used to record hours, minutes, seconds, and 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.
