Curious to hear of people's experiences with the Kolari ultra-thin sensor glass modification. I'm considering it on either an A7RII or the newer A7RIII.

 

Has the camera had any issues since modification? Any regrets on doing the modification?

Sorry, I don't have experience with that modification of the Sony cameras, But I use regularly the Sony A7 II with legacy SLR manual lenses (Leica-R, Contax and Olympus OM).

I found some problems only with some wide angle lenses (for example, with the Summicron-R 35). But others, specially the OMs, works very well even without modification. I use the 21 f:2, 24 f:2,8 and 28 f:2,8 without noticeably problems, the 24 in particular is incredibly sharp from corner to corner from 5,6 on, possibly even at f:4.
