I dunno, this has never been a problem with my XA. Accurate focus and ample depth of field have been the rule. That said, I usually use my rangefinders for subjects between 5 feet and infinity. I DID have two or three times when the electromagnetic shutter "froze", but a few swift whacks into the palm of the hand cleared it up. Perhaps when someone else did the same thing the rangefinder shifted a bit? I did read about the sticky shutter solution on the web many years ago, so it's out there. The focus nub moves so little to begin with...If it's really out of spec its possible someone took it apart and reassembled it wrong sometime in the last 30 years. Stranger things have happened.
