Exactly, the Contax, in addition to the focusing gained from moving the
internals around, can give you another 15mm extension by racking the lens
out. All lens become close focusing. And when will it happen? When CCDs
that are capable of 20 megapixel files are involved so that they can use most
of the glorious sharpness of the Zuiko lens.
