I've recently noticed some dirt (which includes a small hair, which i thought would be easy to remove) when looking through my viewfinder.
It appears regardless of which lens i mount, so im certain the problem doesnt lie in the lens. I've tried to clean my mirror by using a blower, but the dirt still remains there. Also, it doesnt seem to be on the outer surface of the viewfinder.
Where else could the dirt be that i can clean? Although, (of course) it doesnt affect the picture quality, it can get irritating at times considering that it is of a significant size.
Thanks in advance.
