First impressions:
1 - F/8 autofocus is confident in good light. I now run the 5D4 by default with the 100-400 II + the 1.4 TC III, and it locks sharply. I have not tried this yet with birds in flight circumstances, but it works very well with crazy children hopped up on birthday party sugar and car license plates coming and going at 50 mph. I was frankly surprised, as the f/8 center focus point on the 1DX was a bit worse than this.
2 - 30 megapixels matters. The people who were convinced that 20 mp was a point where you'd find a diminishing rate of returns were - for my type of shooting - incorrect.
3 - The autofocus is a league better than the 5D3. I feel it is more confident than the 1DX Mark I. The increased distance between the lowest and highest focus points is appreciable.
4 - There are lots of little easter eggs in the menus, with little improvements having been made here and there. Perhaps these were already in the 5DS series, and I never got the memo, but they weren't there in the 1DX, 5D3 or 7D2.
5 - The shutter feels much, much better than the 5D3, which clacked. Silent mode is optimistically titled, but not the joke it was with the 5D3 or 1DX.
6 - The build quality feels more solid than the 5D3 or 7D2. Saint Roger revealed why with his teardown (interlocking doohickies). But it is noticeably lighter too. I also perceive that the matte finish is more matte, with a real frictive feel to the hands.
7 - The new, customizable Q menu is pretty handy.
8 - 7 frames per second seems slow, now that the 5D4 is arguably a pretty good wildlife body, this is its weakness.
Caught this broad wing hawk on a wire near my house this afternoon. This is roughly a 1-to-1 crop of a JPG (can't abide Canon's DPP software, so waiting for Adobe before going back to RAW) from the 100-400 II at 400 with the 1.4TC III at f/8. No post production...
