Next-Level Stills and Video
Boasting a newly designed full frame, 12.1MP back illuminated Exmor R CMOS sensor and 8x more powerful BIONZ XR processing engine, the Sony Alpha a7S III mirrorless camera breaks new ground in stills and video performance. Along with 4K 120p and Full HD 240p video recording, the camera delivers doubled readout speeds, reduced rolling shutter and 10 fps continuous burst shooting (mechanical or electronic) with AF/AE tracking. It offers astonishing image quality across its ISO range of 80-102400 (expandable to 409,600), and the stunning resolution and depth of field that only comes with a full frame sensor. 15 stops of dynamic range renders colours and textures outstandingly.
Exceptional AF with Enhanced Real-Time Tracking
Focus with pinpoint precision throughout space and time. Using on-sensor phase-detection, the Sony Alpha a7S 3 delivers enhanced AI-based Real-Time Tracking and human/animal face and eye AF, in both stills and movie mode. With astounding speed and accuracy, this detects and tracks your subject—even partly obscured faces— throughout the frame, even with shallow depth of field and in lighting as low as EV -6, leaving you free to concentrate on composition. Focus control can be easily and finely adjusted to help you rack focus or switch between subjects.
Internal Intra-Frame Recording at 10-bit 4:2:2
Record directly to the Sony a7S 3 with the breathtaking realism afforded by 10-bit depth and 4:2:2 colour sampling. This provides incredible flexibility when it comes to grading and post-processing. For more demanding projects the camera can also record 16-bit RAW via HDMI to an external recorder. Inherited from pro camcorders, S-Log3 gamma and S-Gamut3.Cine colour gamut offer broader dynamic range and easier colour matching, while HLG (Hybrid Log Gamma) makes it easy to produce HDR footage. There’s also the option of All-Intra encoding, which encodes each frame independently at up to 600Mbps to more accurately capture complex motions and streamline workflows.
5-axis Image Stabilisation Plus Unlimited Recording
The a7S 3 from Sony makes no compromises on stability or recording time. 5-axis optical in-body image stabilisation (IBIS) with new Active Mode reduces camera shake by a powerful 5.5 steps while preserving image quality. This means you’ll be able to capture smooth, stable footage – even while walking or shooting handheld, and even without a gimbal. A unique heatsink built into the camera’s IBIS unit improves heat dissipation by 5x, enabling no recording time limits in all video modes and 4K 60p recording for more than one hour.
Ultimate Performance and Usability
The Sony Alpha a7S 3 delivers the ultimate in both performance and usability. Frame each shot and view your settings via the fully articulating 1.44 million-dot, 3” touchscreen or stunning 9.44 million-dot electronic viewfinder. Based on professional feedback, the menu and selected dials have been thoroughly revised for faster, more intuitive operation. Dual media slots support both CFexpress Type A and SD cards for superior speed and flexibility, while a digital audio interface with direct 24-bit input enables optimal audio capture. Improved weather sealing ensures dependable performance even in dusty or wet conditions.
