Just a suggestion, maybe put a Canon EF mount on it by default? EF is an almost 'universal acceptor', then you can mount any of Nikon, Pentax, M42, Leica R lenses. The more available lenses the more popular it might be. With a Nikon mount you can only really mount Nikon lenses (and MF goes with everything of course).
