FOR VISUAL TRAILBLAZERS With extreme full-frame movie performance including high sensitivity (expanded ISO up to 409600), 15-stop wide dynamic range, 4K 120p1, fast and dependable autofocusing, and extra-strong image stabilisation, the α7S III again raises the bar for movie makers. Large pixels deliver high sensitivity and low noise The new full-frame 12.1-megapixel2 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. Up to 8x more powerful BIONZ XR 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 power4. 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. Stunning AF performance even at 4K 120p 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. 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 optimisation, the 12.1-megapixel2 full-frame sensor achieves low noise throughout the sensitivity range, and can capture usable images in near total darkness. 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. CFexpress Type A media slots The upper (Slot 1) and lower (Slot 2) media slots both support UHS-I and UHS-II SDXC/SDHC cards as well as the all new CFexpress Type A cards for higher overall capacity and faster read/write speeds. CFexpress Type A cards are ideally suited to high-speed continuous still shooting as well as 4K movie recording at high bit rates, providing next-generation write speeds of still image and movie data. In-body 5-axis image stabilisation A highly accurate image stabilisation unit and gyro-sensor are provided, delivering 5-axis optical image stabilisation. [1] Yaw [2] Roll [3] Pitch Active Mode for hand-held shooting The new Active Mode10 11 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 resolution11. Advanced operability 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. Outstanding continuous shooting performance Use your choice of mechanical or electronic shutter for continuous burst shooting, with AF/AE tracking, at up to 10fps13. Capture decisive moments with over 1000 frames of continuous uncompressed RAW shooting possible14. Fast Hybrid AF for stills The Fast Hybrid AF system combines speed and precision. With 759 focal plane phase-detection sensors and 425 contrast-detection points distributed across most of the image area, the α7S III quickly finds and tracks your subject throughout the frame.
