The 7D2 should have an advantage with the crop, but in several cases I am not seeing that. For example in the coyote shot from earlier I compared it with a similarly posed coyote taken in worse light with my 5D3 but same rough ISO (400) and found that the detail is roughly the same despite the smaller size of the coyote on the 5D3.
In terms of the underexposed images that is what the light was at the time. With my 5D3 normally I would have shot these at ISO 3200, but at the time I was trying to get a good comparison between them. The point of illustration was the noise and loss of detail - not the quality of the shots.
I looked in LR just now to see the average ISO for my shots and can see:
ISO 3200 and above - 20%
ISO 1600 to 2500 - 25%
ISO 800 to 1250 - 20%
This is of all my shots, so most of the shots at lower ISOs were tripod based landscapes while most of the shots at higher ISOs are of wildlife.
If you want to shoot at ISO 3200 and above the 7D II is not the right tool.
The half hour around sunset and just before is a curse for wildlife photographers. Animals start moving, the light is to low. I feel the pain.
I wouldn't push the 7D II past ISO 1600 and expect great results shooting wildlife. At sunrise the 7D II starts work later than the 5D III and will end its day before the 5D III.
My 7D II underexposes a bit over 1/3 of a stop.
