I still say the "7D2" should get a sensor sized other than 1.6x crop. Whether that is "aps-h" or not, doesn't matter as much...as long as it's bigger than 1.6x. As I think I tried to post in one of these threads (but it seems to have been deleted or blocked...if it wasn't, I can't find it)...
What I would like to see, is a "1D Mark 5"...a "1Dx killer"...a crop camera whose sensor is bigger than 1.3x, but smaller than full frame. Say 1.17x...with pixels slightly smaller than the 1D4's. Its photosites were roughly equal to 25 mp if scaled to full frame.
So make this 1.17x sensor equal to 26 mp on a full frame...The width of the sensor would be roughly 31mm, and the actual pixel count would be roughly 19 MP, with frame pixel dimensions 5340 x 3560. This keeps the file size small enough for high speed shooting, and makes use of the best 90% of the lens' image circle...and even makes significant use of wide angle lenses. The total image dimensions allow for roughly 5% better cropping ability than the 1DX allows...and get a lot more than 5% of extra resolving power from even third party supertelephoto lenses...let alone the superlative Canon series 2.
With this, we get a slight crop factor and significantly more reach than even cropping a 5D3's full frame image, and yet we retain much larger pixels than anything in the 1.5x or 1.6x crop arena...for improved ISO noise and dynamic range. Yet the file size is only barely bigger than a 1DX file.
Why tie ourselves to "aps-h", when no lenses are specific to it? It used full frame lenses...
If Canon ever built my proposed "1D5"...I would sell everything I could part with, to buy it...even if it cost similar to a 1DX. Because, given some help with processing and perhaps improved sensor construction, hardware, and AD conversion and layout, etc...the image quality could conceivably be comparable, if not even exceed the 1DX.
This seems like the way to go, especially given the future 46 to 60 MP full frame 1 series body on the horizon. With it, there's no need to keep the sports/wildlife/action camera full frame...because the vast majority of the photography done with one, is not at 14 or 16mm.
