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.
The SLR design solved a lot of problems with the rangefinder design. It also created a new problem, that of size and weight.
The mirrorless design solves the size and weight problem, but it re-introduces most of the problems with the rangefinder design plus a few new ones of its own.
It won't be until there's a mirrorless design that solves the same problems that the SLR design solves that we'll see mirrorless be a viable alternative to an SLR for those who need an SLR today.
And, let's face it. While smaller and lighter is certainly better, it's something a pro can easily live with. Even a 1-series body weighs nothing in proportion to the kit as a whole, especially if you've got enough in there to qualify for Platinum CPS membership without the body.
I repeat: the Canon mirrorless will be a "prosumer" camera, overlapping (and likely eating into) the high end of the PowerShot line and the Rebel line. It won't ever compete with the 5- or 1-series, nor will it compete with the ELPH series. It can't -- by the very nature of the design, it's got all those compromises that prevent it from ever being as good as an SLR, and nobody who wants an ELPH wants to mess with changing lenses.
