Sony A7SII and A7RII Will Have Uncompressed 14-Bit RAW

Sony has announced that user selectable compressed and uncompressed 14-bit-per-channel raw image capture will be featured in the forthcoming A7SII full-frame mirrorless system camera.

Additionally, they have announced plans to add this feature via firmware update to additional cameras, beginning with the recently introduced A7RII. The company says the move comes in response to feedback from its users.

Until now, Sony camera users have had to make do with raw files compressed using a lossy algorithm, leading to sub-optimal results (as compared with other manufacturers’ cameras equipped with similar Sony sensors).

The company has not yet said which other older models will be supported.
