We already reported the breaking news that Sony will add uncompressed 14-Bit RAW on the new Sony a7SII and Sony a7RII (via firmware update), and later to many more cameras. Today Sony Japan official website announced that it will release a firmware update for Sony a7RII to add the uncompressed 14-Bit RAW in mid October.
And DPReview has got the access to uncompressed Raw files to make clear the benefits of the newly-added uncompressed Raw option.
1) No Artifacts on high contrast edges: “no longer introduce errors and artefacts around high-contrast edges.” “And it’s gone: the artefacts present in the compressed Raw file are completely absent in the newly uncompressed files.”
2) No significant difference in dynamic range: “There’s possibly a tiny improvement if you try to brighten very deep shadows”.
3) Twice size
4) True 14-Bit files
5) Unclear on continuous shooting
