Sony Alpha a7 III Mirrorless Camera with FE 28-70mm OSS Lens

Renowned for its redesigned sensor, the Sony a7 III is an all-encompassing device ideal for both photography and videography in various working environments. Perfected for enhanced speed and low-light efficiency, a fresh 24.2MP Exmor R BSI CMOS sensor and BIONZ X processor add to the superior image quality, video potential, and AF capabilities. The a7 III additionally features a revamped body structure, complete with a touch-enabled LCD, upgraded EVF, extended battery life, and two memory card slots.

The Sony Alpha a7 III Mirrorless Camera Body boasts a back-illuminated design and a full-frame 24.2-megapixel Exmor R CMOS sensor, working in tandem with the BIONZ X image processor to deliver stunning high-resolution stills and videos with reduced noise and increased speed. The sensor's BSI design allows for faster data transmission, resulting in 14-bit stills at native sensitivities ranging from ISO 100-51200, expandable to ISO 50-204800. Additionally, the camera supports internal UHD 4K video recording with wide dynamic range using the full width of the sensor. The BIONZ X processor and high-speed front-end LSI work together to provide fast processing times and an impressive 15-stop dynamic range at low sensitivities.

The camera's sensor and processor allow for rapid continuous shooting of up to 10 fps at maximum resolution, capturing up to 177 frames in a row with continuous AF/AE using either a mechanical or electronic shutter. In live view mode, a continuous shooting rate of up to 8 fps is also achievable.

UHD 4K Video Recording in XAVC S Format

Internal recording of UHD 4K movies is possible in multiple frame rates up to 30 fps and uses 2.4x oversampling, which renders greater detail, and full pixel readout is possible, too, for higher quality imagery with reduced moiré and aliasing. Full HD 1080p recording is also supported in frame rates up to 120 fps, and both 4K and FHD resolutions utilize the 100 Mb/s XAVC S format contained within an MP4 wrapper with 4:2:0 sampling.

The high-speed, 120 fps recording also enables 4x and 5x slow-motion movie recording with the frame rate set to either 30p or 24p. In addition to high-resolution internal recording, uncompressed HDMI output also enables the use of an optional external recorder for clean 4K recording with 4:2:2 sampling.

S-Log3, HLG, and Other Color and Gamma Controls

Affording extensive customizable color and gamma controls, the a7 III allows users to adjust the gamma, black level, knee, color level, and more. Shooters can use the same S-Log2 Gamma Curve that is found on high end Sony Cinema cameras that squeezes up to 1300% more dynamic range into the video signal then traditional REC709, for increased post-production flexibility.

HLG (Hybrid Log-Gamma) support is available, along with the BT.2020 color space, for recording within a wide color gamut and, in addition to S-Log2, S-Log3 is also available for producing an effective 14-stop dynamic range with increased grading control in the shadow to mid-tone regions of the image.

Fast Hybrid AF System

An evolved 4D FOCUS system now employs a combination of 693 phase-detection points, which cover approximately 93% of the frame, along with 425 contrast-detection areas for reliable and quick autofocus and subject tracking performance. This Fast Hybrid AF System now achieves twice the focusing speed and more reliable tracking compared to previous a7 models, as well as improved low-light focusing.
