All I've seen, Steve, is some anecdotal evidence. Don't get me started on 
Ken Rockwell, but on this page, he does have some examples of a 21mm Super 
Elmar-M adapted to the A7 that appears to show sensor reflections and 
smeared corner detail. Lurking around the dpreview forums, I've seen others 
report similar results. But of course it's hard to know for sure
