The bigger question I guess would be whether these new USM lenses also have the mechanical linkages to work on older bodies? I have a strong suspicion that they will not, but would love to be wrong... If not then it is less useful to have an ist(any flavour) or K100(unless it gets enabled) as a backup body.

One must have lenses with built-in USM motor for USM to work :-) But I guess new mount would be back compatible, so older lenses would work the way they usually did ;-) Cheers, Sylwek -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
