That's not something I'd ever notice because I _always_ power off my camera to change lenses. Without fail. Not a good idea at all to do that under power. I expect that wiping live contacts across the lens contacts as the lens cylinder rotates into lock will cause untold glitches and ambiguous signals at the very least; possibly dangerous to either the body or lens electronics. I know that changing the flash while powered is bad because I blew up an AF540FGZ that way. $180 to fix that gaff. And pulling or inserting CF cards under power is likely to damage data. Anyone else change lenses without powering down the camera? -- -bmw -- 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.
