The last two times i have gone to use my Sigma 300 F 4 with its Sigma 1.4 tele, i can't help but notice it does not seem to focus properly.I can tell in the finder and on screen as well.
I know the 300 focuses properly on its own, as i have the printed results to show its still quite sharp. There does seem to be a very minor bit off play with the tele at the lens mount and lens mount.Not much a mm or so. Could that be enough to make a wonky connection. I have not cleaned any connections, but they look OK.Both K10D and PZ-1 showed these signs. Any thoughts.
