The new Sony Alpha a7S III will keep you inspired to create images like no other. With extreme full-frame movie performance including high sensitivity (expanded ISO up to 409600), 15+ stop wide dynamic range, 4K120p, fast and dependable autofocusing, extra-strong image stabilisation and 4K60p All-I movie recording time over an hour, it again raises the bar for movie makers.
A revised 12.1MP Exmor R BSI CMOS sensor and updated BIONZ XR image processor offer faster performance, improved noise reduction, and a wider dynamic range, along with UHD 4K 120p video recording and internal 10-bit 4:2:2 sampling.
Video is the primary application of the a7S III, and improvements to the sensor and processor enable faster readout speeds and greatly reduced rolling shutter, along with high-bitrate internal recording, 16-bit raw output via the full-size HDMI port, and flexible control over motion with variable frame rate selection. The a7S III also does away with recording time limits and incorporates HLG for direct HDR production as well as S-Log2/S-Log3 gamma profiles for advanced HDR production with editing.
The updated sensor design brings improved AF performance via 759 phase-detection points, which offer intelligent subject tracking and Real-time Eye AF to ensure critical focus on moving subjects in all recording modes. The sensor and BIONZ XR processor also facilitate impressive sensitivity, with an expanded range from ISO 40-409600, as well as fast 10 fps continuous shooting for up to 1000 consecutive raw frames. Additionally, 5-axis SteadyShot INSIDE sensor-shift image stabilisation is available, too, which minimises the appearance of camera shake by up to 5.5 stops.
Changes to the physical design include a rear LCD with a side-open articulating design and an impressive 9.44m-dot OLED electronic viewfinder. Dual memory card slots both support working with CFexpress Type A or SD UHS-II memory cards for flexible and high-speed file storage. Includes a free Sony 160GB CFexpress Type A Memory Card.
