I was cleaning my D5000 body as usual.
Been doing this at least twice a month since february this year without any problems.
While using the blower, my friend accidentally pushed me and the blower tip made contact with the pentamirror thus scratching it, not the diagonal mirror. (I'm not sure of the term)
It's the mirror/glass where it's facing downwards.
What should I do? When I look through the viewfinder, my heart just sink. It was spotless before and now it's filled with smudges and scratched.
Will it cost a bomb to replace? Thanks in advance.
