I have a Carl Zeiss Jena Flektogon 20/2.8 MC (multicoated) lens in Pentax PK mount--yes, PK mount, not M42. A previous owner must have permanently adapted it. I'm planning to put it up for sale. But before I do, it would be pity if no one tested it on an M43 body and compared it against the Panasonic 20/1.7. I don't have a PK adapter and would rather not buy one just to do this test. Would anyone within 50 miles of Washington, DC, who has a PK adapter, like to borrow my Flektogon and post some sample shots?
