I have a stuck pixel. I had it a couple months ago, did the sensor cleaning trick and went away. Now suddenly it is back with a vengeance. I have done about 10 passes of the sensor clean trick and now the pixel is just stuck. Shows bright pink in nearly every RAW shot at every ISO/SS. Jpeg conversions seem to make it either smaller or bigger, but white . Very annoying! I just cloned it out of a set of 45 pics. I don't want to have to do this the rest of the time I own the camera. The only time it does not show is if I get lucky and it hits something nearly pure white.
Anyway, I still have 5 months warranty left, should I send it in to Canon? Can they do anything? I know crap like this can happen with 10 million pixels but I wonder how much is normal to accept. This is clearly visible at even small output sizes.
