[font color=\'#000000\']In my travels last week looking for info regarding dead pixels on my 10D I did see a reference the situation you discribe. Can't find it now, however it mentioned dust under the IR filter on top of the chip causing this type of spotting you are seeing. I recall it was more apparent at small apatures than longer exposure. My limited expierence with bad pixels on monitors is they show up as pinpoints of bright white light. I'm seeing the same in the images from my camera (see my post from several days ago). Dosen't sound like a bad pixel to me but that is what I was asking about in my post. Maybe 2 is the magic number.

[font color=\'#000000\']Got the 20D last week and get black spots on my images (same location on all prints) which become more prominent after applying USM. Tried 2 lenses to rule that out ... and have found that the spots only show up on exposures of 1 sec or over.
Took it to the dealer they said it was burnt pixels and are going to order a replacement.
Anyone else come across this issue or can explain why the spots would only show up on 1 sec or greater exposures?
Thanks.[/font]
