Bernard,Thank you for you reply.
I have some hair in my prism, I handblowing, clean with digiclean, clean the lens and still, I can see hair after in before take the photo, . I read and read the book,and ask in the internet, but not luck. I can't find how to clean it. The view finder have some hair too and I can't clean it. I clean the viewfinder screen, and the mirror, as well all the lens, but I can still see the hair, and after I take the photos I have to clone stamp in PS all the time.
Thank you again.
I hope the is more clear them the first post.
