Canon should go after the Leica market with its mirrorless design.
At one time Leica was the pro camera of choice, Canon and Nikon also built rangefinders. But all that changed when the Nikon F arrived. Pros abandoned the rangefinder and went with SLRs. Canon switched to building SLRs, Leica added an SLR to their line-up. Time marches on!.
Not many people would buy a rangefinder or hybrid.
Obviously many would buy a mirrorless camera though right? Afterall, Isnt this what the threads about?
Last time, I recall my OM-1 not being much larger that a animal cracker box, compared to how hulking DSLRs have gotten.
