I have just gotten back my Leica 90mm from DAG in which he found a couple of loose elements and it is slightly sharper, but it seems to focus on things in front of what I have focused on. I suspect my rangefinder is off. So before I call up DAG on Monday, I want to do a test this weekend have some film for him to inspect. I was thinking of using a yardstick and place some kind of mark on it. Make some sort of note where I focused and then compare it after the film is developed.
