From the "existing art" section of the controller patent, it seems that the PZ lenses already use a two-way data link.
The new patent application seems to be just an extension of functionality of the existing KAF2 mount; it may not physically be a new mount -- IF TRUE, this would mean that the MZ-S (and others?) could be capable of using the new lenses either straight off or after a software upgrade. ;-) ;-) ;-) -- Kristian On Saturday, Aug 31, 2002, at 13:08 Europe/Dublin, Kristian Walsh wrote: > Hi, > > All the pieces required to digitally control a USM or IF lens are > already in place in the K-AF2 mount.
