hey all, after reading the last 4 page discussion about the 20D front focussing problems, hopefully mine will be simple. i'll start by saying that....
i'm a full blown rookie.
there it's out in the open. now to the problem.
on a bright sunny day, with my 20D, and 70-200 f4, it seems as though when i auto focus on an object past the infinity mark, i think it's about 10 meters for this lens, the camera (lens) cant quite make focus and focuses a little shallow.
i remember reading that the variation on the infinity mark is due to the temperature,(?) and i have to manual focus between 2 millimeters rotation with the focus ring.
without confusing us both even more, it sems from the other posts that my lens may need to be recallibrated? or is it the body?
if you need any more info i'll try to suss it out, but maybe there's an easy fix, maybe firmware or so?
thanks in advance, mark.
