Ok, we have a slight issue here... With my new 5d, I have noticed it attracts dust on the mirror/LCD almost every time I change lenses... Never was an issue with my 7d or 5d2 or prior cameras. Anywho today I took a canon brand rocket blower today to knock out the dust and looked into to viewfinder to find 2 small streaks in the scene. After looking around it was the plastic screen above the mirror assembly. I took a dry clean anti static cloth... Nope... Tried blowing warm air on it (like you would glasses) and wiping thoroughly, looked clean but streaks were still there. Ok, seriously annoyed now I get rubbing alcohol and qtips and lightly clean it... That's when things started taking a turn for the worst... I start getting a faint circle outline and more streaks, as if by doing so is removing some coating on the underside of the plastic. Anywho after trying to clean it as best as I could, looking through the VF has a large circle outline that extends from the top to the bottom of the screen perfectly around the center "spot" circle in the middle, and various imperfections in areas... Basically the top plastic in front of the transmissive LCD is going to have to be fixed/replaced. Anyone had any issues like this with maybe the 7d or 5d3? Looking through the VF is saddening, AF and the actual transmissive part appears perfectly fine, and photo is perfect as always... Any suggestions before I prepare to get raped my canons repair services?
