I've got a few specs of dust showing up in my viewfinder that are driving me nuts. I tried to blow them out, but that didn't work. So I took the brush on my lenspen and tried to brush them off of the mirror and focusing screen but I'm afraid that did more damage than it did good. Now I've got slight streaks on the mirror because of the brush!
So, how do I get the mirror clean and how do I get rid of that pesky dust?
Btw, I never had dust get into my K-7... but maybe that was because I didn't change lenses as often back then...
