Sony A7R IV: Where is the Firmware Update to Upgrade Us to Lossless-Compressed RAW Files?

re: Sony A1
re: data compression
re: Sony Announces an Uncompressed File Format for A7R II and Future Cameras

See the updated version of this post.


Lossless-compressed raw is bit-for-bit identical in data (once uncompressed) to uncompressed raw. Uncompressed raw is the stupidest most useless format around, as all it does is waste storage space and waste time writing to card, backing up, etc. And Sony’s “Compressed” raw format has image quality problems under conditions of extreme contrast.

Fujifilm gets lossless-compressed raw right, as does just about every other camera vendor.

I have hundreds of gigabytes of uncompressed Sony raw files sucking up 2X the space they need. Sure would be nice to have a tool to redo uncompressed Sony ARW raw files so as to cut the size in half (on average)

Will anything but the Sony A1 offer lossless-compressed raw file format?

Sony has promised that the Sony A1 will incorporate a lossless-compressed raw file format, something I’ve been waiting on for years with the Sony A7R/II/III/IV.

In addition to compressed and uncompressed RAW, the Alpha 1 includes efficient lossless compression with no quality degradation, Lossless Compressed RAW.

The Sony A1 is not out yet, but the Sony A7R IV sits here waiting for a firmware update to give it the lossless-compressed raw file capability.

Will Sony be delivering firmware for the Sony A7R IV to give it lossless-compressed raw file format support?
