The adapter came in the mail today so this is from my first photowalk with the Sony A7 and 50mm Olympus/Zuiko manual focus lens from the 70s.
3 things that surprised me:
The Sony colours straight out of camera were not as bad as I had feared
The focus peaking on the Sony is very good.
That old lens is very sharp
I shot it at F/1.8... just because that's what you do when you have a fast lens on a full frame camera :-)
