    i have a canon 300d and i noticed a small speck of dust in my viewfinder that i couldnt get out simply by wiping the eyepiece. it isnt in my pictures, so i know its not on the sensor, but when i tried cleaning the mirrors, i made things worse (a lot worse). what can i use to clean the mirrors without putting more dust on them.?

    Be very, very careful when trying to clean a mirror!

    Best not to touch it at all. If you must try something, use one of those hand bulbs and use a very gentle puff of air. Even compressed air can be too much. It's very easy to goof them up.

    You can knock the mirror out of allignment and it won't flip correctly or won't show the correct view. I haven't done it myself, thankfully.

  8. The big difference about the in-camera mirror and what you know as a mirror from home is that the one at home is mirrored behind a layer of glass. The one in the camera actually has the mirror right on top - otherwise it would be too heavy, and the focal differences would have to be calculated differently. Anyway, the one inside the camera is hyper sensitive - as markc says: because of aligment and other mechanical issues, but also because if you touch it, getting your finger grease off is MUCH harder.
