I'm a new photographer, in exploring the new camera EOS -5D, and I need a help to clean inside, mirror, sensor and all glases. I tried to use dust cleaner spray (Century Duster), I did not touched any parts of mirror or sensor, but I realize when I look through viewfinder a lots, hundreds of litlle particle of black dust. I there any chance, to solve this problem without send it back to store ? It is brand new, I got it just 2 weeks ago, and I can not take any more pictures at this moment. It is anyone to help me ?
Help...., Help ...
