I actually asked Sony Support about that. Their reply: "We can confirm that with Lossless compressed RAW there is a minimal quality loss. To have no impact on image quality I suggest using Uncompressed RAW files." Lossless isn't what it used to be.

That's insane. I honestly thought that lossless basically means to run zip over the file and not more. Gotta hate companies these days with their dishonesty. "Lossless" means "lossy". "Unlimited" means "limited to 50GB".

Seems you just got 1st line robo-reply repeating what public resources state. Does not say much about actual compression algorithm Sony uses.

  Their first reply was "we have passed your question to a higher technical team", then they came back four days later with the above reply. I was enquiring about the A7R mark V, which introduced the much needed "lossless" option. I think I asked because I wondered why they kept the uncompressed option and because experts warned that Sony did that before with "lossless" formats.

    It is a shame that Sony has such an obsession with weird proprietary formats.
