Hi, I need some expertise to determine whether I shall return a MX or a FA 35/2 (or both?) to focusing adjustment. Let me try to explain the problem:
During my recent vacation I put the FA 35 on the MX to do some late evening b/w shooting. During this I noticed that it was impossible to focus the lens on infinity - the lens just couldn't be turned that far. So, I tried a few things: - I put the lens on the MZ-3 and tried to focus on some very distance subjects. No problem, although that might occur since the DOF of the lens is big and the AF accuracy slightly smaller than the accuracy of the MX split image. On a few occasions, the MZ-3 would focus the lens without turning the lens to the end (ie, changing to manual focusing it was possible to turn the lens a little further). - I focussed some other lenses on the MZ-3 on distant subjects and checked the same subject on the MX. With both the 77/1.8 and an old MF Tokina AT-X 100-300/4, the same focus setting was correct on both bodies. I bought both the FA 35/2 and the MX this summer, and test rolls revealed no visible errors. So, what is your opinion? Are there other tests I should perform? One obvious thing I will do tonight is to mount the Tokina telezoom on a tripod and focus on a faraway object with the AF body, and then switch to the MX to check. But, besides that? Are these kind of alignment problems common on either lenses or (MX) bodies? Hoping for guidance! best regards, Erik - This message is from the Pentax-Discuss Mail List.
