Friend of mine who used to build laser spectrometers (now builds mass spectrometers) swears by using dish soap with your fingers for cleaning optical glass. Never done this with a camera lens -- kinda hard to stick it under the tap for rinsing -- but it's what I do with my glasses. If the glass bed comes *out*, which it after all almost has to do, that might be your best bet for cleaning it. No risk of introducing anything damp or conductive to the circuitry. -- Graydon -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
