I have mixed feelings about the 7D II having used one a lot alongside a MkIV and 1DX.
- The AF is quick I'll give it that - easily on a par with the 1DX and slightly better in low light - but I've found in servo (AI) mode it doesn't lock on as well as either of the 1 series bodies I use, even when set to it's slowest point for tracking. In part I think this is down to it needing a degree of MFA on the 600mm lens I use, something the 1 series bodies have not needed, but I want to be confident in what I use and out of the box I just don't have that confidence with this body.
- The ISO noise is little better than the Mk IV.
- For resolving things at distance the MkIV is much better (as is the 1DX).
Your mileage may vary and I may have received a copy that needs some tweaking. I'm not saying the 7DII is a bad camera and it is an improvement on the original 7D, but I'm sticking with the MkIV and 1DX.
The price is the price and will fall over time as these things do, but £12k UK = a lot more than Euro 11.8K, so basically Canon are saying buy from a Euro shop if you live in the UK or someone fluffed the press release.
