I received my 7D2 last Thursday and immediately set out for wildlife to photograph. My primary interest is wildlife photography and I spend one hour in a park every day before going to work. I currently use a 5D3 with a 200-400/1.4x and a 6D as my backup body (mainly for landscapes).
Going in I expected ISO 1600 on the 7D2 to be roughly the same as ISO 3200 on my 5D3. On my 5D3 at ISO 1600 I can still count the feathers on a bird, while at ISO 3200 the feather detail begins to break down but the image is still usable for most purposes.
What I found was that on the 7D2 there was still a noticeable lack of detail at ISO 1600 compared to ISO 3200 on my 5D3. Even worse, when I went down to ISO 800 there was still noticeable noise, though the images were certainly usable. This morning I spent some time photographing identical subjects with the two, and I came to the conclusion that the 7D2 simply would not work for me.
I am glad I bought it at unique photo - who said they'll take it back as long as the box is in good condition. I had hoped this would give me a bit more extra reach, but again I found myself learning the painful lesson of cropped sensors. Instead I intend to wait and see what Canon does with the 1Dx2.
Unfortunately my sample images are not up, but you can get an idea from this one (ISO 400).

What's wrong with the image?
