Up to 120fps continuous shooting with Speed Boost
Continuous Shooting Speed Boost allows you to temporarily increase the shooting speed during burst shooting, elevating the frame rate to 120 fps. This feature is particularly effective when capturing sports and other high-speed events, where you can anticipate the timing of the desired action.
Up to 120 AF/AE tracking calculations per second
The high-speed readout of the new image sensor empowers the α9 III to perform up to 120 AF/AE tracking calculations per second, doubling the capability of its predecessor. The AF excels at tracking intricate subject movements and anticipates sudden shifts with unparalleled accuracy. Simultaneously, AE effortlessly adapts to abrupt changes in brightness. Notably, the Alpha 9 III maintains tracking even during continuous shooting, further enhancing precision for photographers who capture highs-speed action.
1/80000 second shutter speed
Seize every moment of high-speed action at sporting events and beyond. The global shutter sensor enables an astonishing maximum shutter speed of 1/80000 second for still images. This capability extends to capturing even the split-second departure of a bullet from the barrel of a rifle at shooting competitions, exemplifying the A9 III’s extraordinary speed and precision.
Flash sync at any and all shutter speeds
This ground-breaking feature enables the use of flash to provide additional subject illumination when shooting outdoors in bright daylight with a high shutter speed. It minimises the reliance on extensive lighting setups, significantly broadening creative shooting opportunities.
BIONZ XR image processing engine
Inherited from the flagship Alpha 1, the BIONZ XR image processing engine delivers up to 8x more processing power than previous generation processors, significantly reduces processing latency while substantially enhancing image processing capabilities.
This results in images with rich colour gradation, lifelike colour reproduction, and minimal noise. The engine efficiently handles the extensive data produced by the newly developed Exmor RS image sensor in real-time, even during continuous shooting at speeds of up to 120 fps. Furthermore, it can capture high-quality 14-bit RAW images across all still shooting modes.
Wide coverage fast and precise autofocus tracking
The Sony a9 III mirrorless camera is equipped with a Fast Hybrid AF system, merging the speed and tracking accuracy of phase-detection AF, with the fine precision of contrast-detection AF. This combination ensures dependable subject acquisition and tracking, even for subjects with quick and erratic movement. The camera boasts an impressive 759 phase-detection points distributed across a high-density focal plane phase-detection AF system, covering nearly 95.6% of the image area.
Reliable subject recognition of more subjects
The A9’s AI processing unit offers enhanced subject recognition, spanning Human, Animal, Bird, Insect, Car/Train, and Airplanes. Within the Car/Train category, it can even identify helmets, such as those worn by formula race car drivers.
Animal recognition now extends to the eyes of grazing and small animals, in addition to recognising the eyes, heads, and bodies of dogs, cats, and similarly featured animals.
Bird recognition has also seen improvements, making it easier to pinpoint the eyes of various bird species and recognise their bodies. Furthermore, a new Animal/Bird setting streamlines the process, eliminating the need to switch between two settings when capturing images of animals or birds.
Human pose estimation using skeleton-based model
Leveraging its innovative AI processing unit, which was first seen in the A7R V and has subsequently rolled out to cameras like the A7C II and A7CR, the a9 III harnesses subject form data to achieve precise movement recognition. The technology extends beyond merely recognising eyes to accurately identifying body and head positions.
This means the camera can effectively lock onto and track a subject facing away from the lens or one with their face obscured. Even a distant human subject occupying a relatively small portion of the frame (even smaller than in previous Real-time Recognition AF iterations) can be identified, provided they are in proximity to the focus area when the shutter is half-pressed during continuous AF shooting. This capability enhances focus acquisition, particularly when capturing an athlete approaching from a distance, as seen in track-and-field or ski events, for instance.
Composite RAW Shooting to reduce noise
Composite RAW Shooting enables the capture of multiple images (4, 8, 16, or 32, selectable), which can be subsequently merged using Sony's Imaging Edge Desktop™ computer application software. This process produces full-resolution images with minimal noise, even at higher ISO settings, making it perfect for high-speed wildlife photography and low-light portraits. Moreover, when shooting at lower sensitivity levels, the α9 III can utilise handheld camera shake to create images with reduced false colour and jagged artefacts through Composite RAW processing.
Completely distortion-free movie recording
The newly designed full-frame global-shutter sensor, featuring stacked CMOS architecture, brings substantial advantages to both movie production and stills photography. With the absence of rolling shutter distortion, it becomes possible to capture natural-looking footage, regardless of the subject or camera movement. This holds true even when filming from a fast-moving vehicle or executing swift camera pans..
4K 120p without cropping for the first time in an Alpha body
A noteworthy first in Sony's Alpha lineup, the a9 III introduces 4K (3840 x 2160) 120p movie recording without cropping. This enables creators to maximise the full angle of view provided by any Sony Alpha lens. For instance, whether shooting 4K footage in slow motion at 120p or standard speed at 24p within the same scene, the angle of view remains consistent. This allows for seamless editing without the need for reframing and cemnets the A9 III as an advanced hybrid filmmaking tool.
Cinematic S-Cinetone™ colour profile
Sony's S-Cinetone picture profile inherits colour science responsible for delivering stunning colours and natural skin tones found in the advanced Cinema Line range. S-Cinetone yields authentic mid-tones crucial for lifelike skin tones, along with gentle hues and accurate highlights. This empowers creators to focus on their shooting, effortlessly achieving a cinematic look, without the necessity for extensive colour grading in post.
5-axis optical image stabilisation for 8-stops compensation
Capture handheld shots with confidence thanks to the third-generation Sony a9 III’s high-precision image stabilisation unit, advanced gyro sensors, and refined stabilisation algorithms. This system adeptly identifies and rectifies camera shake, delivering an impressive 8.0-stop stabilisation when handholding.
When combined with lenses featuring built-in image stabilisation and enhanced communication between the camera body and lenses, you gain effective control for capturing sharp, blur-free shots, even at extended telephoto focal lengths.
Dynamic active Mode stabilisation
The camera incorporates a high-precision stabilisation unit and gyro sensors, complemented by fine-tuned image stabilisation algorithms. This synergy enables advanced electronic stabilisation to collaborate with the camera's 5-axis optical in-body image stabilisation system. Additionally, the Dynamic Active Mode significantly enhances stabilisation, surpassing the existing Active Mode by more than 30% (approximately).

Drive Mode and Focus Mode dials
The camera features stacked drive mode and focus mode dials, which can be operated independently for swift access and selection. Users can easily choose between single or continuous drive mode and single or continuous AF focus mode without the need to navigate menus using buttons. Both dials are lockable, preventing inadvertent mode changes during use. Additionally, a new functionality allows the drive mode dial to be deactivated and reassigned to the FN menu or a custom button, which proves valuable for shooting in low-light conditions or when using a rain cover that might obscure the dial.
The upgraded OLED viewfinder boasts an impressive 9.44 million-dot (approx.) resolution, featuring a 0.90x19 magnification and a 41° field of view for a clear, expansive sight. It incorporates an updated structure with a 25 mm high eye-point, delivering an immersive viewing experience with minimised aberrations around the viewfinder image.
Notably, both viewfinder and monitor lag times have been minimised to enhance framing stability, especially during continuous shooting. Users can choose from three finder frame rate settings: Standard (60 fps), High (120 fps), or Higher (240 fps). The 240 fps option provides an exceptionally smooth viewfinder image, reducing motion blur significantly when capturing moving subjects and during panning or tilting.
Greater flexibility from a new front custom button
