Thought I get some advice here. Got a dSLR and notice that there was a dark spot when looking through the viewfinder.
The dark spot appears to be a dust particle as it was not there in the first place. Blowed the mirror and interior and viewfinder with a blower and the dust still there. Interchange the lens has no effect, which means it's in the camera.
However, it does not affect the picture taken. Took a picture against a white surface and image is clean.
Anybody got any idea what it could be? Should I be bothered by it since it does not affect my pictures at all? Advice?
