New Alpha 1 Firmware Update Enables 8K 4:2:2 10bit Recording and Lossless RAW File Options

SAN DIEGO, CA – June 13, 2022 – Sony Electronics Inc. today announced the v1.3 firmware update for the flagship Alpha 1 full-frame mirrorless interchangeable lens camera, adding 8K 4:2:2 10bit recording and Lossless Compressed RAW for still images.

Using newly added 8K 4:2:2 10-bit capabilities, filmmakers and cinematographers can more precisely customize the vibrancy and color grading of their recordings. Combined with the Alpha 1’s 8.6K oversampling for extraordinary 8K resolution, the new addition of 4:2:2 10-bit recording lets filmmakers and content creators realize their creative vision with incredible realism and color.

The update also adds Lossless Compressed RAW files in S, M, and L (small, medium, or large) file sizes. Selecting L size preserves the same image quality as an uncompressed RAW format while significantly reducing the file size. The M and S sizes record fewer pixels than the L size, providing more manageable RAW files. With Alpha 1 v1.3, users can freely combine JPEG and their choice of Lossless Compressed RAW sizes based on their use case. This is especially beneficial with a user needs to deliver JPEG files immediately, but also needs RAW files for in-depth editing.

Updates to the Alpha 7S III

A new v2.1 firmware update for Sony’s acclaimed Alpha 7S III full-frame mirrorless interchangeable lens camera is also available for immediate download. Most notably, this latest update includes the introduction of proxy recording during remote computer connect and improvements to Eye AF (autofocus) performance.
