I have an mono/IR modded A7R5 which turned it into a thin sensor stack, so lenses native to the Sony mount perform poorly, while lenses native to a thin sensor perform wonderfully.
This is a very interesting statement: I asked this about performance of E-mount or DSLR based attached lenses on Sony A7-based MLCs with modified thinner sensors in the past, and others here posted that there is no disadvantage of using larger DSLR-based lenses even on such modified sensor with thinner sensor cover glass more optimized for rangefinder lenses. I always wondered about this since the sensor cover thickness should be optimized to the lens system in use.
When you say "poorly", can you further elaborate on this? I would be very interested to hear where the differences become obvious even this is off topic here.
I cannot comment on how DSLR lenses perform on a stock thick-stack Sony. But I can comment that native wide angle M-mount lenses perform fine corner-to-corner, quite contrary to what others have shown with the same lenses on their stock Sony.
