It's based on electro-magnets which are on the floating plate on which the sensor is mounted acting against permanent magnets affixed to the body (front plate of SR assembly). So there is nothing to anchor the floating plate until the electro-magnetic coils are energized. -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
