I was addressing specific cameras. Of course, the 5Ds(r) has similar pixel density to the 7D2, but it has a little more noise at 100%, and shoots at half the speed. My hope for the future is a 7D2-class crop camera with read noise per unit of sensor area as good or better than the 5D4 or 1DxII (I think the D500 is already better, if I'm not mistaken), and a slower-shooting very-high-res 6D-like camera. I may cave on the 5D4 while waiting, though! If it had f/11 center-point AF to accommodate 1.4x more TC magnification with AF than the 7D2, it would be more certain.
F11... you must have some weird lenses.... the slowest lens I have is F4 and all my other lenses are 1.4, 2 or 2.8 and for some reason I have never been able to understand that F number doo hickey thing. The lenses just shoot at that number they have on the barrell and I thought that was your only option.
I mean doesn't everyone shoot wide open???
