Ok, I just got a new lens (85/1.8 - love it so far) that I was testing out today when I got the following results. Pic 1 is 1/2000 at f2.0, Pic 2 is 1/800 at f2.8 - both ISO 100. The problem in Pic 1 is worse at higher shutter speeds - meaning the dark area is larger. I think my shutter may be dying on me, I have about 6300 shots on the camera so far and have had it for about 18 months so far. If it is a shutter repair I think I remember someone saying that it was $250 or so, don't think that is economically feasible as these cameras are around $400 new.
What I would like to know is my assumption right, I don't want to send this off to Canon to have them tell me what I suspect. Is there a way to remedy this myself, I don't really have the warm fuzzies getting into the camera as I can still shoot as long as the shutter speed is less than about 1/1000. Do I have much longer on this, I would've thought this would show up at all speeds not just higher ones.
Thanks in advance.
