But it's a piece of hardware that's already a part of current lens mounts, and probably hasn't changed one little bit in 20 years of Pentax cameras. Engineering is already done, and the space constraints of that area of the cameras are set by other factors (size of the mirror, lens mount to film distance). All of my Pentax cameras have had VERY similar lens mounting arrangements.
