I have the same problem in the corner of my view finder the rest of it is just gray.........I can't take pictures or view the ones in my camera.........any suggestions on how to fix this??
If the dust/dirt is visible in the finder, it is in one of three locations: - if very sharp, it is on the "grind" side of the viewing screen, which, unfortunately for cleaning ease [unless the screen is user-removeable], is often the upper side of the screen in newer cameras. - if fairly sharp, it is on the non-"grind" side of the screen, and it may be possible to remove it with a VERY soft (very clean!) small brush or a VERY gentle blowing with a hand syringe-type blower (blowing hard into a VF area just about guarantees that dust will be blown in). - if very soft-looking, it is on the underside surface of the pentaprism (being able to clean the VF area without a repair is an excellent arguement for having the interchangeable-screen feature...). Prevention is the best way - never leave the body cavity uncovered (except briefly, when changing lenses); never change lenses in a windy area; keep the rear area of the lens clean; get in the habit of facing the open camera downward while changing lenses; NEVER blow into the body cavity (unless you know what you are doing, the mirror is up, or the screen is removeable). Hope This Helps
