You are correct but the problem is that the lenses are still optimised for 36x24mm or were until they were nobbled. The register distance is a function of the required mirror clearance which is determined my reflex mirror size/film format. So given the register distance lenses providing a "normal" angle of view need to be retro-focus designs instead of gaussian making them much larger for comparable performance. -- 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
