Sony FE 35mm F1.4 GM Full-frame Large-aperture Wide Angle G Master Lens
For visual trailblazers
With extreme full-frame movie performance including high sensitivity (expanded ISO up to 409600), 15-stop wide dynamic range, 4K 120p 2, fast and dependable autofocusing, and extra-strong image stabilization, the α7S III again raises the bar for movie makers.
Large pixels deliver high sensitivity and low noise
The new full-frame 12.1-megapixel 3 back-illuminated Exmor RTM CMOS image sensor packs major innovations in light-gathering, wiring and output optimization. These deliver blazing doubled readout speeds, superb image quality throughout the whole sensitivity range, 15-stop 4 wide dynamic range, and reduced rolling shutter, with the sensor also providing focal-plane phase-detection AF.
Up to 8x more powerful 5 BIONZ XRTM image processor
Along with the new sensor and its unprecedented speed, the BIONZ XR image processing engine has also been newly developed and packs up to 8x more processing power 5. With a future-oriented architecture, it delivers high quality images faster for superlative still and video expression, as well as dramatically improved camera interface responsiveness.
Our renowned sensitivity delivers expanded ISO 409600
The renowned sensitivity of the series scales new heights, with an expanded ISO range for movies from 80 to a remarkable 409600 (standard range 80–102400). With advanced light-gathering and output optimization, the 12.1-megapixel 3 full-frame sensor achieves low noise throughout the sensitivity range, and can capture usable images in near-total darkness.
10-bit 4:2:2 recording
Record right on the camera with the amazing richness of 10-bit depth and 4:2:2 color sampling, for far greater flexibility in image grading, post-processing and compositing.
Superior quality and smaller files with XAVC HS
The new XAVC HS recording format uses HEVC/H.265 encoding to achieve twice the compression efficiency of AVC/H.264 encoding, for superior image quality and smaller file sizes 6.
16-bit RAW HDMI output
For demanding post-production workflows, 16-bit RAW output 8 is available via HDMI connection to compatible external recorders 9 while XAVC HS 4K, XAVC S 4K, or XAVC S-I 4K, and proxy files are simultaneously captured in-camera.
Image quality improvements
The new BIONZ XR image processing engine delivers improvements in color reproduction, stability against different light sources, natural tonal gradation and roll-off, and reduced rolling shutter.
Unique heat dissipation, for dependable recording
A unique Sony Σ (sigma) shaped graphite heatsink is built into the image-stabilization unit. This dissipates heat 5x more effectively 14 for extended recording time, without interfering with image stabilization.
Two CFexpress Type A-compatible media slots
Both card slots support both ultra-fast CFexpress Type A cards, allowing high-bitrate recording and fast buffer clearance, and SDXC UHS-II cards. Parallel and Relay recording are also available.
Vari-angle LCD monitor for comfortable movie shooting
The variable-angle 1.44 million-dot 19 3.0-type touch screen features a side-open design, for flexible positioning and improved visibility when mounting on gimbals or rigs.
9.44 million-dot 19 high-definition electronic viewfinder
The new EVF offers resolution, contrast and color unlike anything in its class 20. It also offers world-leading 0.9x finder magnification 21, a 41 ° diagonal field of view, and a 25-mm-high eyepoint.
Powerful focus control for solo shooters
With AF Transition Speed selectable over 7 levels, and AF Subject Shift Sensitivity over 5 levels, you can better convey your creative intentions when switching subjects or, for example, rack focusing. A simple touch can temporarily activate AF even during manual focus operation.
Superlative movie performance
Digital audio interface for clear sound recording
A digital audio interface added to the Multi Interface (MI) Shoe allows direct 24-bit input. Available settings are 48 kHz/16-bit 2-ch, and by using the optional XLR-K3M adaptor kit, 48 kHz/24-bit 2-ch and 48 kHz/24-bit 4-ch.
Wired LAN connectivity
For complex, interference-prone environments, or higher bandwidth needs, 1000BASE-T wired LAN connectivity is available by connecting a compatible USB-Ethernet adaptor cable to the camera's USB Type C® port.
Designed with the environment in mind
Sony is committed not only to offering products, services and content that deliver exciting experiences but also to working towards our goal of a zero environmental footprint throughout our business activities.
