Piles of hot pixels on 40D, won't go away with sensor cleaning.
May 15, 2009

My 40D refurb from Adorama arrived today, took some long exposure shots (10, 20, 30 secs, etc) and noted a lot of hot pixels, in the triple digits, way more then my XT ever had. Most noticeable at 30 seconds then less and less as the exposure gets quicker. I tried the tried and true sensor cleaning method and it seems to have had no affect at all. Is there a more serious problem at foot?
