Ok I cleaned my dslr mirror with a special pen provided by nikon which supposedly is suppose to clean my mirror properly. However, my friends told me that I must NEVER touch the mirror.So I went home to check out my camera and looked through the viewfinder and luckily, didn't see any scratches or smudges. However im afraid I have damaged my mirror somehow. Can someone tell me what are ways and the signs and symptoms I can use to identify damage on my dslr mirror
