Also think it's a mirror or screen position problem

Focalpoint gave me a guesstimate of $125 plus return shipping. I am having a hard time thinking that it is a screen / mirror problem on both cameras I am using it on. I need to find another Contax body to test with. Mine is a 167MT btw.

Thanks.

Not sure how to adjust the mirror in the 167 but the Contax 139 adjusts like a Yashica FX3 and is shown here (posts 8 onward). http://www.apug.org/forums/forum52/9...nical-slr.html

Most people would have a hard time thinking that the lens shifts focus during the exposure then shifts back when the mirror comes down. But maybe it is somehow that you are holding the camera causes it to do that.

How would that happen?

Umm, no. It is a consistent occurrence. For further confirmation, I'll check with a tripod when I get a chance.
