Lots of discussions on if APS-H is really dead, or has an opening to return...
Why would Canon do that - it's loose-loose for them, they'd sell less expensive tele lenes for the well-off people while loosing ef-s compatibility and alienating the 7d crowd who bought a 17-55 or 10-22 lens.
The only reason for Canon would be if the competition went ahead and many Canon users would consider switching, but in Nikon-land it's also either 1.5x crop or ff.
because no competition have anything like APS-H, the image quality drop vs full frame is minimal unlike the wonderfull APS-C.
I really believe canon missed an opportunity to storm the mirrorless market, they should have made the EOS M APS-H and the EF-M mount APS-H with a crop mode for use of EF-S lenses.
Instead the horse took off last and is still running the wrong direction!
Basically anything APS-C can do APS-H can do better apply any tech increase to both formats and APS-H will win hands down all the time the marginal additional crop factor of APS-C is not enough to counter the significant benefits of the larger format. And same goes FF is better than both although the gap between FF and APS-H is not as vast as to APS-C
I believe the 7DII will still be APS-C but I think it would be awesome if they made it APS-H with an APS-C crop mode that came with an increase FPS say 6 FPS APS-H and 9 FPS APS-C crop mode then people wont cry about not being able to use the EF-S lenses. If it used a digic 5+ like the 5Dmk3 and had say a 22MP APS-H sensor it would give about a 13MP APS-C image in crop mode with 5Dmk3 build quality. forget the gimmicks like flippy screens, wifi and gps leave all that for the other models, and of course dual card slots and a revamped AF system.
something like this would be a perfect complement to my 5Dmk3
However what is concernng by canons own naming convention the 7D2 sits behind the 6D... and since the 6D is somewhat underwhelming in everything other than the sensor department I am afraid the 7D2 will be another dropped ball.
