Firmware Updates For Sony Alpha 1 & Alpha 7S III

Sony has announced firmware version 1.3 for the flagship Alpha 1! This firmware update adds 8K 4:2:2 10bit recording and Lossless Compressed RAW for still images. Sony also announced firmware version 2.1 for the acclaimed Alpha 7S III, which includes the introduction of proxy recording during remote computer connect and improvements to Eye AF (autofocus) performance.

Firmware version 1.3 for the Alpha 1 has newly added 8K 4:2:2 10bit capabilities, giving filmmakers and cinematographers more precision when customizing the vibrancy and colour grading 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 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 version 1.3, users can freely combine JPEG and their choice of Lossless Compressed RAW sizes based on their use case. This is especially beneficial when a user needs to deliver JPEG files immediately, but also needs RAW files for in-depth editing.

Alpha 1 version 1.3 is available now and can be downloaded below:

Alpha 7S III version 2.1 is available now and can be downloaded below:
