Laying claim to the title of world's first global shutter mirrorless camera, the Sony a9 III is a speedy and incredibly capable system for sports, wildlife, photojournalism, and much, much more. This revolutionary sensor technology raises the bar for full-frame imaging, including the ability to shoot raw continuously at up to 120 fps and enjoy flash sync up to the maximum shutter speed of 1/80,000 second. Blending the functionality of this 24.6MP sensor with Sony's powerful BIONZ XR processor and AI Processing Unit results in a system that will provide unmatched performance for those looking for an incredibly responsive and reliable camera system.
Global Shutter—A First for Mirrorless
Sony has delivered the world's first full-frame global shutter mirrorless camera with the a9 III. The use of a global shutter provides a leap in performance over the rolling shutter technology used for decades. A global shutter provides a near instantaneous and simultaneous readout of all 24.6MP, eliminating skew and other artifacts that plagued rolling shutters. It also far surpasses mechanical shutter technology is every way, making the physical shutter unnecessary in the a9 III.
Global shutters help ensure consistent and uniform exposure across the entire frame in all lighting conditions. Flash sync is possible at any shutter speed-even the maximum of 1/80,000 second. The simultaneous readout also prevents banding from certain light sources, such as fluorescent lighting. In a gym, outside, or with mixed artificial lighting the a9 III will handle it with ease.
Flash photography and mixed lighting conditions will see major usability enhancements with the use of a global shutter. This includes the ability to sync at up to 1/80,000 second with any flash. Sony flashes will benefit from communication that ensures optimal results and third-party flashes can be synced with the shutter by using a menu setting to adjust the delay.
Pre-Capture & Speed Boost—Never Miss a Moment
Along with the key technology delivered by the sensor, the a9 III offers features new features to unlock the camera's full potential.
Pre-Capture: The a9 III can be configured to begin recording images to the buffer when the shutter button is half-pressed. Users can set this between 0.05-1.0 second. Upon pressing the shutter these images will be saved to the memory card.
Speed Boost: Not every shoot calls for the a9 III's impressive max speed of 120 fps. With Speed Boost and the C5 button, which is conveniently placed near the grip on the front of the camera, users can instantly switch their camera from their usual continuous shooting frame rate to a faster one to make sure their next shot is just right. Photographers will be able to select various frame rates up to 120 fps.
Pro-Quality 4K Video
While video benefits greatly from the use of global shutter technology-rolling shutter and banding artifacts are completely eliminated-the a9 III boasts plenty of other video improvements over its predecessor worth talking about.
The a9 III captures and downsamples the full 6K image area to produce high-quality UHD 4K video up to 60 fps. It can also record 4K up to 120 fps with no crop.
Record 10-bit 4:2:2 internally using All-I encoding for maximum quality.
Output 16-bit raw via the full-size HDMI port to a compatible external recorder.
S-Log3, S-Cinetone, and other Picture Profiles are available for optimizing the image for your workflow and production environment.

Sony FE 16-35mm f/2.8 GM II Overview
Wide-Angle Versatility for Stills & Video
Combining G Master performance with the lightest and smallest form factor in its class, Sony rounds out its trinity of f/2.8 G Master zoom lenses with its latest wide-angle offering for video and stills shooters, the FE 16-35mm f/2.8 GM II Lens, which boasts a variety of optical, focusing, and handling upgrades.
G Master Image Quality
Designed to rival the primes, this zoom's optics have been revamped to provide even greater resolution, clarity, and bokeh quality.
Bright f/2.8 constant aperture allows users to capture images in dim lighting conditions and with a shallow depth of field.
One Super ED (extra-low dispersion) and Two ED elements effectively suppress chromatic aberrations and color fringing for greater clarity and color fidelity.
Five aspherical elements, including three extreme aspherical elements (XA), minimize spherical aberrations, distortion, and also reduce 'onion ring' bokeh.
Faster AF and Floating Focus Mechanism
Faster focusing performance, improved close-up shooting, and enhanced control are all benefits of the redesigned focusing system.
Four XD (extreme dynamic) linear motors contribute to greatly improved focusing performance, compared to the DDSSM system of the predecessor, including faster, quieter, and more precise AF that's ideal for both video and stills.
Faster AF means improved focusing when working with fast-moving subjects; support is available for shooting at up to 30 fps, full AF is maintained even when shooting stopped down, and focus tracking is possible even when changing the zoom position.
Floating focusing mechanism helps maintain image quality throughout the focusing range, which is especially important considering the impressive close-up performance of this lens: minimum focusing distance of 8.6" and a maximum magnification of 0.32x across the entire zoom range.
Internal focusing design promotes snappier, more responsive focusing performance and maintains the same center of gravity during lens extension and retraction.
Improved Control and Video Capabilities
Just as camera design has grown to appeal to both photo and video shooters, this lens has also been updated with a series and attributes that specifically appeal to video shooters' needs.
Focus breathing, focus shift, and axial shift during zooming have all been minimized to prevent unwanted movements and angle of view variations for greater compositional accuracy during recording.
Supports the Breathing Compensation function in select cine-line and Alpha cameras.
Linear Response MF provides natural, intuitive manual focus control.
Manual aperture ring can be de-clicked for silent operation and the zoom smoothness can be adjusted depending on the desired torque.
Compact, Lightweight, and Robust Design
The smallest and lightest f/2.8 wide-angle zoom in its class, this lens doesn't lose sight of its professional attributes and remains a weather-sealed, durable lens for use in trying working conditions.
Approximately 20% lighter and 10% smaller than its predecessor, this zoom is a highly portable and versatile option for a huge variety of shooting applications.
Now fit with a manual aperture ring, tactile exposure control is possible. This ring can be de-clicked for smooth and silent iris pulls or it can be locked in the 'A' position for camera-based aperture switching.
Two programmable focus hold buttons and a focus mode switch for intuitive focus control.
Hybrid construction uses both metal and plastic components to maximize both durability and a low weight design.
Dust- and moisture-resistant design includes rubber gaskets at each seam and a rubber ring sealing the lens mount for ensured use when working in inclement weather conditions.
Front lens element has a fluorine coating that repels water, oil, and other contaminants and makes the lens easier to clean.
Included lens hood has been redesigned to complement the lens' sleek design by reducing both its diameter and length.
