Alpha 7S III with pro movie/still capability

The new full-frame 12.1-megapixel 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-stop wide dynamic range, and reduced rolling shutter, with the sensor also providing focal-plane phase-detection AF.
The new Exmor R full-frame image sensor and revolutionary BIONZ XR image processing engine deliver always-active pinpoint AF for astonishing detail in both space and time, and stunning 4K movies even at 120 frames per second or in slow motion. With the resolution and depth of field only possible from a full-frame sensor, the results are spectacular.
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-megapixel full-frame sensor achieves low noise throughout the sensitivity range, and can capture usable images in near total darkness.
The wide-area AF uses intelligent tracking and on-sensor phase-detection covering most of the frame. The result is that every bit of supremely accurate and tenacious AF performance is extracted in combination with high-quality E-mount lenses, even when shooting moving subjects at shallow depths-of-field in 4K and at 120p frame rates.
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.
The new Active Mode provides increased stabilisation for movie shooting. To preserve image quality, the BIONZ XR processor accurately measures camera shake and compensates optically. This makes stable video possible even when shooting hand-held where space restraints prevent gimbal use, while walking, and at 4K resolution.
Learn the four unique advantages of using Sony's E-mount lens for video shooting. The combination of Sony's lenses and cameras will enhance your video creation experience.
With an amazingly wide standard ISO range of 80–102400 (expandable to 40–409600 for stills), the α7S III offers incredible creative opportunities. The newly developed image sensor and image processing algorithms produce even cleaner images and more natural textures than the previous α7S II model, even when shooting in near total darkness.
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.
The variable-angle 1.44 million-dot 3.0-type touch screen features a side-open design, for flexible positioning and improved visibility when mounting on gimbals or rigs.
The new EVF offers resolution, contrast and colour unlike anything in its class. It also offers world-leading 0.9x finder magnification, a 41 ° diagonal field of view, and a 25-mm-high eyepoint.
The menu structure has been redesigned to reflect feedback from both pro photographers and videographers. Camera settings are now more intuitive and the camera is more responsive to setting changes.
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.
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.
Elevate your photography with Imaging Edge Desktop applications. Use "Remote" to control and monitor shooting live on your PC screen; "Viewer" to quickly preview, rate, and select photos from large image libraries; and "Edit" to develop RAW data into high-quality photos for delivery. Get the best from Sony RAW files, and manage your productions more efficiently.
Capture One Express (for Sony) is free award-winning editing software that provides RAW development, easy management and powerful editing tools. Capture One Pro (for Sony) is also available for even more editing tools and tethered shooting capability.
