Marnie, I believe that dust on the lens elements is usually so completely out of focus that it can't show up as a discrete particle. Too much of it can, of course, scatter light and reduce contrast. Dust on a sensor, OTOH, sits close to the plane of focus and casts a distinct shadow. Regards, Jim -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
