The Sony A7S mark iii E-mount Camera has evolved in both Stills and Movies, taking the S series to a whole new level of full-frame movie expression. The A7Siii has spectacular new speed which combines with supreme sensitivity and ultra-low noise to put previously impossible 4K movie shoots on the menu, with high dynamic range, breathtaking focusing, and extra-strong image stabilisation.
Large pixels deliver high sensitivity and low noise
The new full-frame 12.1-megapixel1 back-illuminated Exmor RTM CMOS image sensor packs major innovations in light gathering, wiring and output optimisation. These deliver blazing doubled readout speeds, superb image quality throughout the whole sensitivity range, 15-stop2 wide dynamic range, and reduced rolling shutter, with the sensor also providing focal-plane phase-detection AF.
Up to 8x more powerful3 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 power3. 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.
10-bit 4:2:2 recording
Record right on the camera with the amazing richness of 10-bit depth and 4:2:2 colour sampling, for far greater flexibility in image grading, post-processing and compositing.
All-Intra encoding available
As well as Long GOP, All-Intra encoding is now provided. This encodes every frame independently at bitrates up to 600Mbps, to capture complex motions more accurately for recording on either internal or external media, and allow more efficient editing workflows.

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 sizes2.
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 optimisation, the 12.1-megapixel3 full-frame sensor achieves low noise throughout the sensitivity range, and can capture usable images in near total darkness.
S-CinetoneTM from high-end cinema camera colour science
The inclusion of Sony’s acclaimed S-Cinetone4 look, inherited from the development of the Cinema Line FX9 and CineAlta cameras such as VENICE, allows cinematic colour to be achieved directly in-camera. S-Cinetone is optimised for natural skin tones and mid-range colours, with gentle highlight roll-off, for impressive subject depiction without grading at post production as a workflow.
S-Log3 gamma, S-Gamut3.Cine gamut as on pro camcorders
The S-Log3 gamma curve and S-Gamut3.Cine colour gamut, shared with pro camcorders, provide wider dynamic range and easier colour matching for smoother post-production workflows.
HLG (Hybrid Log-Gamma)
HLG (Hybrid Log Gamma) simplifies HDR production, producing footage for HLG-compatible BRAVIA TVs on the camera with no complex post-production, and smooth gradations from the 10-bit colour depth.

Image quality improvements
The new BIONZ XR image processing engine delivers improvements in colour reproduction, stability against different light sources, natural tonal gradation and roll-off, and reduced rolling shutter.
16-bit RAW HDMI output
For demanding post-production workflows, 16-bit RAW output5 is available via HDMI connection to compatible external recorders6 while XAVC HS 4K, XAVC S 4K, or XAVC S-I 4K, and proxy files are simultaneously captured in-camera.
Efficient editing through proxy recording
While recording high-bitrate 4K movies, HD proxies (in 8 or 10-bit depth) can be generated in-camera7. Editing the smaller proxy files reduces computer load and speeds up workflow prior to final 4K delivery.
Real-time Eye AF for movies
Real-time Eye AF uses AI to ensure pinpoint focusing precision for eyes, with performance now improved by 30%2 on profile or partially-obscured faces. Tenacious eye tracking lets you concentrate on composition even with a shallow focus depth.
Real-time Tracking with intuitive touch operation
Real-time Tracking analyses subject colour, pattern, depth, and face information to track the subject. Touch Tracking intuitively and automatically tracks a subject touched on the LCD screen.
In-body 5-axis image stabilisation
A highly accurate image stabilisation unit and gyro-sensor are provided, delivering 5-axis optical image stabilisation.

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 48kHz/16-bit 2-ch, and by using the optional XLR-K3M adaptor kit, 48kHz/24-bit 2-ch and 48kHz/24-bit 4-ch.
Unique heat dissipation, for dependable recording
A unique Sony Σ (sigma) shaped graphite heatsink is built into the image stabilisation unit. This dissipates heat 5x more effectively5 for extended recording time, without interfering with image stabilisation.
Movie-shooting comfort
Responding to feedback from professional users, the MOVIE button has been moved to the top face for improved operability in any shooting position. Mode dial ordering and speed of switching have also been improved.
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-dot1 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-dot1 high-definition electronic viewfinder
The new EVF offers resolution, contrast and colour unlike anything in its class2. It also offers world-leading 0.9x finder magnification3, a 41° diagonal field of view, and a 25mm high eyepoint.
New menu structure
Based on requests from our most demanding professional users, major improvements have been made to the menu structure, for improved at-a-glance readability and reduced menu navigation.
Intuitive touch operation
The menu screen can be operated by touch, while the playback screen features swiping, and pinch-to-zoom. Operability of the touch functions when shooting has also been improved.
Remote preview and shooting
Either wired or wireless remote shooting is available from a PC, or from a mobile device with Imaging Edge MobileTM installed, for more efficient workflows and shooting in challenging environments.
