.optimized for improved speed and low-light performance, enabling an impressive continuous shooting rate of 10 frames per second and improved autofocus performance for faster and more reliable subject tracking.

The updated Fast Hybrid AF system uses a combination of 693 phase detection points and 425 contrast detection areas for very fast focus acquisition in almost all lighting conditions and maintains focus on the subject more effectively. In addition to speed and autofocus, the processing improvements also ensure clearer images with greatly reduced noise throughout the sensitivity range of ISO 100-51200, which can even be extended to ISO 50-204800

. Video recording capabilities have been enhanced for improved quality when recording UHD 4K video with the full width of the full-frame sensor to minimize moiré and aliasing. Additionally, the a7 III utilizes 5-axis SteadyShot INSIDE sensor-shift image stabilization, which minimizes the occurrence of camera shake by up to 5 stops.

Aside from the imaging system updates, the body design of the Sony a7 III has also been revised to include a rear 3.0" 922k-dot touchscreen LCD, which features a tilting design to better support high and low angle work. A Tru-Finder OLED EVF viewfinder with 2.36 million pixels is responsible for bright and clear subject recognition,

two SD memory card slots are now available for greater shooting flexibility, and a larger NP-FZ100 battery can now also be used to provide up to approximately 710 shots per charge. The body is made of a robust magnesium alloy for use in tough conditions, and this and the a7 III's weather sealing also make the body resistant to dust and moisture.

24.2MP Exmor R BSI CMOS sensor and BIONZ X image processor

The 24.2 megapixel Exmor R CMOS sensor works with the BIONZ X image processor to deliver high-resolution still images and video while minimizing noise and improving speed. This sensor design works with an on-chip lens design and anti-reflective coating, as well as the elimination of the optical low-pass filter, to improve shooting quality and increase detail.

In addition, a copper wire layer improves data transfer speed for the creation of 14-bit high resolution stills with a native sensitivity of ISO 100-51200, which can be extended to ISO 50-204800. In addition, the internal UHD enables 4K video recording with a wide dynamic range utilizing the full width of the full-frame sensor.

The BIONZ X processor also works in conjunction with a high-speed front-end LSI to realize faster processing times while capturing an impressive 15 stops of dynamic range at low sensitivity levels. The sensor and processor combination also enables fast continuous shooting at up to 10 frames per second at full resolution, for up to 177 consecutive frames and with full-time AF/AE, whether using the mechanical shutter or the electronic shutter. When shooting in Live View mode, a continuous shooting rate of up to 8 frames per second is still possible.

Fast Hybrid AF system

An advanced 4D FOCUS system now uses a combination of 693 phase detection points, covering approximately 93% of the frame, together with 425 contrast detection areas to ensure reliable and fast autofocus and subject tracking. This fast hybrid AF system now achieves twice the focusing speed and more reliable tracking compared to previous a7 models, as well as significantly improved focusing in low light.

The use of phase detection points now enables the use of A-mount lenses via the optional LA-EA3 or LA-EA1 lens adapters with full continuous AF/AE tracking compatibility.

The Sony a7 III offers extensive customizable color and gamma controls, allowing users to adjust gamma, black level, knee, color level and more. Users can also utilize the same S-Log2 gamma curve found on high-end Sony Cinema, which brings up to 1300% more dynamic range to the video signal than the conventional REC709, increasing flexibility in post-production

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