The Alpha 7S III offers in-camera 4K recording up to 120 frames per second, 10-bit depth and 4:2:2 colour sampling, producing stunning video recording. The new camera offers a more flexible and efficient post-production workflow with a variety of advanced movie recording modes such as All-intra and MPEG-H HEVC/H.265 coding (XAVC HS™). The Alpha 7S III makes it easy to integrate video recordings with other professional camcorders by providing three color gamut settings: S-Gamut, S-Gamut3, and S-Gamut3.Cine. Using S-Gamut3 or S-Gamut3.Cine, users can easily match footage shot on the Alpha 7S III with footage shot on the professional camcorders to simplify multi-camera post-production workflow. In addition to S-Log3 gamma curves, the Alpha 7S III supports an HLG (Hybrid Log-Gamma) picture profile, with minimum post-production. The Alpha 7S III also allows 16-bit RAW output to an external recorder via HDMI Type-A, offering additional post-production flexibility.

Improved Image Quality

The new CMOS image sensor and BIONZ XR™ image processing engine in the Alpha 7S III delivers legendary S-series sensitivity with significantly enhanced color reproduction and texture renderings for improved overall image quality. The base ISO has been lowered to 80, resulting in a normal range of 80-102400 (expandable to 80-409600 for video and 40-409600 for stills) to provide more flexible ISO plus wide dynamic range with low noise at all settings. It offers improved image quality by approximately 1 stop of noise reduction in the middle and high sensitivity ranges.

Versatile Operability

Advanced Autofocus Performance for Hybrid use

The Alpha 7S III offers Fast Hybrid AF by combining phase-detection and contrast-detection AF, giving it the ability to track subjects over a wide area with outstanding speed, precision and smoothness, even when using a narrow depth of field. Fine focus expression is possible with Sony’s E-mount lenses.

For environments with a lot of movement, Real-time Tracking and Real-time Eye AF are available to maintain constant focus on the intended subject. Sony’s advanced Real-time Eye AF improves detection performance by 30% over previous system, thanks to the new image processing engine. It ensures accurate, reliable detection even when the subject’s face looks away. Real-time Tracking is initiated simply by touching the subject on the screen. Simultaneously, Real-time Eye AF is initiated when an eye is detected.

Flexible Autofocus Settings for Movie Shooting

Based on customer feedback, the camera includes several AF features for professional users including AF Transition Speed in seven settings, to easily create rack-focus transitions, and five AF Subject Shift Sensitivity settings, which allows the user to customize how easily AF will switch or stay with the locked-on subject. Touch Tracking allows user to not only initiate Real-time Tracking but also compose and shoot while using a gimbal or while shooting solo. It’s now possible to Touch Focus during manual focus mode on the LCD screen or remotely from the Imaging Edge Mobile application[1]

New Heat-dissipating Structure

The Alpha 7S III’s design has been overhauled to ensure effective heat dissipation and prevent overheating – even during extended continuous recording sessions at 4K 60p 10-bit 4:2:2 video for an hour or more9. A newly developed unique heat dissipating structure, keeps image sensor and image processing engine temperatures within their normal operating ranges, preventing overheating while maintaining compact body dimensions.

Movie Assist Functions

For video on-the-go, the Alpha 7S III is the first Alpha series camera to include Active Mode  for supporting especially difficult handheld movie shooting with 5-axis optical in-body image stabilization.

In addition, the Alpha 7S III provides a selection of new Creative Look with 10 presets, that can be used for both photo and video shoots, making it easy to create interesting moods right in the camera to be used as is or customise by the user.

A digital audio interface has been added to the camera’s Multi Interface (MI) Shoe for clearer audio recordings from a compatible Sony external microphone. Used with the Alpha 7S III, the XLR-K3M XLR Adaptor Kit additionally provides 4-channel 24-bit digital audio recording capability in an Alpha series camera for the first time. Like other MI shoe accessories, no cables or batteries are required, providing unrestrained freedom for Alpha system moviemaking.
