Sony has released firmware updates for its flagship Alpha 1 (Version 1.30) mirrorless camera and its Alpha 7S III (version 2.10) full-frame mirrorless camera.

The Sony A1 firmware update brings 8K 4:2:2 10-bit video recording capabilities from 8.6K oversampling.

The A1 already had 10-bit recording capabilities, but it was only 4:2:0.

The update offers a lot more latitude in post-production for colour correction and grading, as well as for tools like chroma-keying.

The Sony A1 also receives lossless compressed raw format still files.

Of the A1’s V1.30 firmware update Sony stated, ‘Using newly added 8K 4:2:2 10-bit capabilities, filmmakers and cinematographers can more precisely customise the vibrancy and colour 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 realise their creative vision with incredible realism and colour.

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.’
