Thanks (and for all the articles you provide … I’m anticipating and looking forward to a wealth of information in upcoming blog posts).
I infer the line that shows blue/cyan is the a7RII. Or not?
Can you tell what is going on at ISO 640 with the a7Rii? Seems odd.

The blue line is the a7RII.
I think that at ISO 640, the conversion gain is increased by switching out a capacitor in parallel with each photodiode. Sony licensed technology that can do that from Aptina several years ago, and it looks like they’re using it in the a7S.

Thank you for the many informative and unbiased posts; I only discovered your site a couple of months ago, and am reading up on older reports. As for the a7rII, I wonder if you have found any explanation for the “orange peel” look to developed RAW files. I noticed it in the first a7r I had, and it seems to persist with the latest iteration. As you probably are aware of, Lloyd Chambers is going on a bit about it and ascribes it to the lossy RAW files of the Sony. Any thoughts on this?
