After five years in the making, the Sony Alpha a7S III Body is finally here to raise the bar with a revised 12.1MP Exmor R BSI CMOS sensor and updated BIONZ XR image processor offering faster performance, improved noise reduction, 15 stops dynamic range along with UHD 4K 120p video recording and internal 10-bit 4:2:2 sampling!
The Sony a7sIII does away with recording time limits and the improvements to the sensor and processor enable faster readout speeds and greatly reduces rolling shutter and enables high-bitrate internal recording plus 16-bit raw output via the full-size HDMI port. This camera also incorporates HLG for direct HDR production as well as S-Log2/S-Log3 gamma profiles for advanced HDR production with editing.
Autofocus is on a whole different level to the predecessor with 759 phase-detection points for intelligent subject tracking and Real-time Eye AF – ensuring 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 stabilization is available, too, which minimizes the appearance of camera shake by up to 5.5 stops.
Sony has also made some changes to the a7S III’s physical design, including a rear LCD with a side-open articulating design and a best-in-class 9.44m-dot OLED electronic viewfinder. The camera’s menu system has also been updated for more intuitive navigation and the body design helps to promote better heat dissipation for improved continuous recording capabilities. Additionally, dual memory card slots both support working with CFexpress Type A or SD UHS-II memory cards for flexible, future-proofed file storage.
