While you guys are having fun with it... let me add that dropping backward compatibility in K-mount � la Nikon means that from this moment on, Pentax will be competing with C/N/M based on strictly their FA lens lineup quality, features, pricing and completeness.
For new buyers (which are only buyers) the current line-up is what its all about. And you forgot the A and F lenses which constitute the bulk of all K mount lenses. In addition, most of the M lenses ecxist in A version as well.
Take out the A and F lines of lenses too. Now that the compatibility dance has started, no sane buyer would want anything but the latest model.
cheers, caveman
