There have looong been rumors about Canon and their mythical medium format DSLR. Canon has mentioned they are "working on something" a few times, but nothing has ever materialized. I can generally understand their reluctance to put much time, effort, and money into developing such a thing, as it does tend to be incredibly expensive. Things have changed in recent times, though, with the advent of mirrorless cameras. They are all small-format right now, smaller than APS-C for the most part.
I'm curious, though, about the possibility of a mirrorless/EVF medium format camera. Looking at the likes of the H4D and Pentax 645, MF cameras tend to be rather hefty and bulky. That could change if someone took the mirrorless approach. Personally, I LOVE the design of DSLR cameras, I like focal plane shutters, I like the size, weight, and ergonomics of DSLR bodies and lenses. However MF cameras just seem to be a tad too large. With smaller size could come reduced cost, and better ergonomics.
Would anyone be interested in such a thing...a mirrorless EVF medium format DSLR from Canon?
