Cut out a small section where the adhesive is...oh. I dunno, maybe an eighth to a quarter inches in diameter. About the size of a "petite" pea. Stick it right in the middle of the lens. Focus at a normal middle distance and look through the viewfinder. Surprised? Something that big _will_ cause a very slight reduction of contrast. But you'd be hard-pressed to see it in a print. And the film won't see it any better than you do. So much for a dust mote. --Mike * * * * * * * * * * * * * * * * * * * * * * * * * Mike Johnston's online articles about photography: http://www.luminous-landscape.com/m-johnston.htm http://www.mir.com.my/rb/photography/opinion/mikejohnston/index.htm http://www.mir.com.my/rb/photography/opinion/html/sharpness.htm - This message is from the Pentax-Discuss Mail List.
