Feeling in a silly mood so.... cropped-sensor (woohoo, half-frame) sized digital black-and-white only, M-mount camera. No bayer-array and no anti-alias filter with a switcheable ir-filter, also no swing screen on the back. Ideally with very useable results to, say, above 3200iso. Viewfinder about 0,72 or a little larger. Plus, of course, the wider lenses to get the best from the format. Battery should be some standard size and the body should have dual-card slots for flexibility and redundancy. The camera would be unique and could lead to a colour version too I suppose, based on economy of scale if nothing else, but based on the wow-factor of the black-and-white version it would have some cachet attached.
