Originally posted by c a sugg I usually shoot manual with the meter set to spot. Occassionally I'll get a reading that makes no sense, then look down to find the selector lever in the center weighted averaging position. I think it may be getting pulled by the camera strap when I have a heavy lens mounted. Has anyone else had that problem?
I do that too !!
I get out there, take 50 to 100 shots thinking all will be fine until I get home to view the pics on the computer .... only to find out that my shots are all improperly exposed .... check the lever: sure enough! It has been moved to centre weighted avg position !!!
For my part, I don't even know how this happens but I think your suggestion of the strap hitting the lever would be a possible cause.
