I've had a 7D2 for a short while, so I'll share my thoughts, what I will say, I've had a 7D for 5 years, and it has stood up well for all my wildlife/sports shooting in that time, rarely missed a beat, and produced some excellent images. And I've never ever subscribed to the notion that the 7D ISO capability is crap above ISO400, I regularly shoot at ISO1600 and even push a little further if I can nail the exposure, producing crisp, clean images.
Anyway, the 7D2 is a nice evolutionary upgrade, feeling similar in hand to the original.
Specifically, ISO capability, mainly for my own use (and not to be considered particularly scientific), I compiled a chart looking at the 7D against the 7D2 at different ISO, taken with a 300mm F2.8 lens, shot in RAW, no noise reduction, with 200% crops of a selection of the RAW files.
The original image, the arrow indicating where I took a 200% crop slice from (as it seemed to contain the most noise)
The comparison table at each ISO
From the table, there doesn't seem to be a great deal of difference between each model, perhaps 1/2 a stop in favour of 7D2 ?, what I have noticed though, is that the 7D2 images 'scrub up' a little better than the 7D images, resulting in a cleaner final image, don't know if this is because of the slightly larger file size?, taken together resulting in perhaps a 1 stop advantage to the 7D2.
In respect of autofocus and tracking, the 7D2 has been an absolute revelation, the 7D autofucus/tracking was very good in decent light, particularly as I always had fast primes attached, which helped, but suffered in low light, the major weakness of the original 7D IMO. While the 7D2 is in a different league, it performs exceptionally well in low light, this morning I took the dogs out walking over the fields, before sunrise, just as it was starting to get light, a friend of mine had a black border collie, chasing a thrown frisbee, the 7D2 locked on and stayed glued to the dog , even while it was running towards me, very, very impressive. This for me, filled the major deficiency in the original 7D.
Like others I had some hesitation in upgrading, I was more than happy with my 7D, but I'm pleased I did, the 7D2 has built on what was a good camera, and added a few useful bells and whistles that I haven't yet got round to trying.
I don't think the 7D2 will be replacing my 1DS3 anytime soon for landscapes/people, but I can't wait to try it out on the Harewood red kites.
