The SR system in the K10D appears to have a 3mm clearance between each edge of the sensor and the supporting frame. So I would expect at that the SR compensation capability is configured for at least +/-2.5mm, what would be the purpose of leaving that much clearance otherwise?. Granted that sounds excessive but given some of the long lens SR tests I've seen posted doesn't appear to be unrealistic. -- 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 [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
