I recently tried to dislodge a piece of lint from my focusing screen using a rocket blower (w/o success) and now I believe I created another problem. The focusing points are now very faint especially viewing them in total darkness. What could be causing this? Could I have dislodged the focusing screen using the rocket blower?
BTW, it seems that the piece of lint is already on the top side of the focusing screen...is the screen easily removable?
