My K10D sometimes shows hot pixels at high iso as well. At other times, the hot pixels don't show up when I pixel peep for them.
I remember coming across a Canon Forum where a member had hot pixels.
His solution was to remove the camera battery for 2 days. After the battery was reinserted, voila the hot pixels disappeared.
yes. notice that from the first photo posted. the noise seems to have some sort of "pattern" instead of random noise due to high ISO. thread starter might want to do more testing to see if its really a problem.:think:
