I scratched the living crap out of my rear screen on the weekend. I had the camera around my back, just at the right height of the metal button on my back pocket. The damage is mostly to the anti-reflective coating as I can't feel the scratches with my fingernail, but it looks bad.
I've found a few websites that have instructions for changing the rear screen protector, but can find a source to buy them from.
The Canon part numbers are CB3-4949-000 for the protector and CB3-4948-000 for the gasket and seem to be in the $50 range. These are from a 5DMk2, but I assume they'll fit a 50D?
Does anyone know where I can get these from. I'll be calling Canon on monday to try but are there other sources?
