Sony a9 III Initial Review by PetaPixel

The Sony a9 III (Amazon/B&H Photo Video/Adorama) is a highly anticipated camera set to release in the spring, featuring a brand new sensor with a global shutter. The sensor enables high-speed shooting, capable of capturing up to 120 frames per second with full autofocus and 14-bit raw capabilities. The camera boasts a new body design characterized by rounded corners and beveling, departed from the classic boxy shape. It also includes top custom buttons and useful ports such as full HDMI, PC sync, ethernet connection, USB-C, and headphone/microphone jacks. The electronic viewfinder (EVF) has a high resolution of 9.44 million dots, without dropping resolution at higher refresh rates.

The Sony a9 III‘s global shutter eliminates rolling shutter issues and can detect and adjust exposure for flicker under artificial lighting. It introduces a precapture mode, allowing users to buffer frames before pressing the shutter, enabling capturing of decisive moments. Additionally, the camera offers high-speed sync without banding and allows for incredibly fast shutter speeds without the need for high-speed sync like traditional TTL flash systems.

For shooting at 120 frames per second or 60 frames per second, faster cards are essential as slower cards result in longer buffer fill times. The lossless compressed format allows for approximately 127 shots before the buffer is filled. Overall, the Sony a9 III promises to deliver a significantly improved photography experience with its advanced sensor, high-speed shooting capabilities, new body design, and various functional enhancements.
