Originally posted by hjoseph7 I managed to remove the annoying dust spot. I had way too much time on my hands so with a pair of small tweezers I carefully removed the focusing screen. I then blew on both sides of the screen and then gently put it back. To my surprise the dust spot was still there. So I removed the focusing screen again and this ran it under some cold water in the sink. I carefully dried with anti-static cloth, hit it with the blower and replaced it.
I look through the view finder and the dust-spot is still there. Wow, this is getting frustrating. So with a magnifying glass I inspect the focusing screen, but I can't see anything ? The dust spot must be somewhere else ? That's when I noticed that behind the area where the focusing screen goes, there is another piece of glass I think it's a magnified glass... I took the Q-tip and wiped the magnifying glass down, then I hit it a couple of time with the blower and "Voila" the dust-spot was gone ! My camera is like brand-new.
You're lucky. I saw dots in my viewfinder. I used clean air from my airbrush compressor to try and blow it clean. I touched nothing, but managed to blow more dust all over the damn screen, mirror, and sensor.
There goes $70 to my local camera repair shop.
