I just read where Lloyd Chambers (Digital Lloyd) is seeing some pronounced Posterization with some A7r ll files. Anybody seeing evidence of this?

Doesn't seem to be. Seems very odd that it isn't.Is the raw file available for others to try? <--- Probably a stupid question.

Here is a RAW file I took with my A7RII that has some water ripples with blue and green tones:

I'm away from home and don't have ACR on this computer. Can someone process it there and tell me if you see posterization? I don't see any in the C1 conversion.
Nope, it's an ARW file. I have written and asked him to try it in C1 or to let me have the original file via dropbox so I can try it.Someone at DPR mentioned that the EXIF for Lloyd's file mentioned that he used JPEG Quality "8". Could this be an issue?
Sorry not buying that argument.We all know that Sony uses lossy compression so Im not sure why we're surprised when sometimes the cost of that becomes evident. Clearly the files can't be as good as those from a D810 - they contain less information.
