Did I ruin my mirror!?
I am relatively new to photography and made the stupid mistake a few months ago of cleaning my mirror on a Nikon FE2 and a few lenses with my t-shirt while out taking photos one day. I didn't realize this could have done damage until I read a few threads on here which were stating how fragile the mirror is and that if it needs cleaned you should send it to a professional.
So do you think I've have ruined the mirror? How about the lenses? With the naked eye, everything appears ok, but I don't know.
Any feedback would be great.
