Those situations though, are admittedly getting fewer and fewer. The biggest difference remains autofocus, but that gap is closing quickly.
The other "biggie" is lens availability. For example, for the new cameras, Sony is going to introduce a 70-200 f4 lens at a premium price. Why not 70-200 f2.8? Technologically, there is nothing that prevents a 70-200 2.8, except for the fact that such a lens is HUGE, and would defeat the key selling point of a "small" mirrorless system.
So I wonder ultimately, for those consumers who do use some big zoom lenses, would they prefer to have their massive lens on a tiny body, or is the balance better putting such a lens on a big dSLR body. Functionally, the cameras would perform the same way of course.
Of course, the overwhelming majority of non-professional consumers don't own 70-200 2.8 lenses..... Most just own a kit lens, maybe also a kit-type zoom. For such buyers, it's hard to see many advantages of a dSLR over a good quality mirrorless.
To me, also in danger, could be the micro 4/3 mount. If you can start putting fullframe sensors in the same-sized body... if pricing isn't astronomical, then what is the advantage of micro 4/3? Slightly smaller lenses?
