A blower's good. But the K20 & thus I assume the 7 too has a thing in the menus where you can vibrate the sensors, and that's done the trick a few times for me. Failing that, you use the other thing in the menus to tell you exactly where the dust is. I bought a pack of pre-sealed pre-moistened swabs-on-a-stick from "Visible Dust" and you just can't miss with them. The package of 20 or so was kind of pricey, but it's lasted a couple of years. We prime-lens victims are subject to serial sensor smut following on unsafe glass interchange in really unsuitable conditions. -Tim -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
