Sony A9 III Full frame mirrorless camera body

Features of the a9 III

A new dimension of still image performance created by the world's firsti global shutter image sensor:

The new a9 III is equipped with a newly developed world's first global shutter full-frame stacked CMOS image sensor with approximately 24.6 effective megapixels and built-in memory, combined with the latest image processing engine BIONZ XR®. It achieves blackout-free Continuous Shooting with AF/AE tracking of up to approximately 120 frames per second. The new a9 III is equipped with high-density focal plane phase detection AF. A designated AI processing unit uses Real-time Recognition AF to recognise a wide variety of subjects with high precision. By combining high-speed performance of up to 120fps with highly accurate subject recognition performance, it is possible to easily photograph decisive scenes and moments that cannot be captured with the naked eye. The AI processing unit in the a9 III supports movies as well as stills with accurate subject form and movement recognition, providing a significant improvement in human eye recognition performance with Real-time Recognition AF and Real-time Tracking automatically recognising, tracking, and focusing on the eyes of a specified subject. The a9 III is equipped with 8.0 stops of optical 5-axis in-body image stabilisation, allowing for high-quality image rendering.

Shutter speed is freed from the limitations of conventional mechanical shutter image sensors and achieves a maximum shutter speed of 1/80000 second (1/16000 second during continuous shooting)vii, making it possible to capture at high speed without any distortion. When a compatible Sony flash is attached, such as the HVL-F60RM2 and HVL-F46RM (sold separately), it is possible to synchronize the flash and take pictures at all shutter speeds up to 1/80000 second. Previously, if the user released the shutter at a speed faster than the flash's synchronisation speed, the amount of light would drop sharply, but with the full-speed flash synchronisation function, it''s now possible to photograph scenes that could not be easily captured with conventional technology. Also, when shooting stills or movies under LED lighting, the Hi Frequency Flicker function can significantly reduce high-frequency flicker problems by allowing the shutter speed to be finely adjusted to match the flicker frequency while viewing the monitor.

The a9 III features selectable release lag modes which allows the user to prioritise release lag or viewfinder/monitor display. The newly installed Pre-Capture function allows the user to go back up to 1 second and record the moment before pressing the shutter, a Continuous Shooting Speed Boost change during shooting, and enhanced burst stamina ensures that important moments are reliably captured due to a large buffer memory and increased overall system speed allow up to approximately 390 Fine JPEG images to be captured in one continuous 30 fps burst.

Customisable focus areas have been expanded to include from XS to XL instead of the previous S,M, and L sizes. The Preset Focus/Zoom function allows preset focus and zoom settings to be memorised in the camera for quick recall when needed. In addition to the existing custom white balance frame size, the user can now select other sizes as needed which allows for fine white balance adjustment after an image has been composed. The a9 III has upgraded features such as the latest AF algorithms to achieve high AF precision down to light levels as low as EV-5 in AF-S mode (ISO 100 equivalent, F2.0 lens), AF tracking for continuous shooting at F22xiv and a composite RAW shooting function that gives the ability to combine multiple consecutive images into a high-quality composite.
