This camera is for sure that what I expected and even a little more.
In good light the 7D is a good performer. However, once you used the AF of the 5D3 or the 1Dx, you see the differences over there. My major issue with the 7D currently is the AF working compared to the 5D3 or the 1Dx. With the last 2, an out of focus picture is rare. The 7D it's AF, which is much better as older APS-C cameras of canon, can't get the same keeper rate as the 5D3 or the 1Dx. To me this new released specification shows at least the same level, and even a probably better AF system compared to the 1Dx. So that's marvelous.
The rest of the spec is what I really expected. Of course the 10fps makes this camera even more attractive to me.
I know some would have expected an increased video performance. I'm glad that Canon really focused this camera as a solution for a APS-C body for sports and wildlife. So I'm very happy they didn't add a lot of specifications for the video users. Please don't understand me wrong, canon might build a body for that area, but the 7D was and will, as the current spec shows, stay an action camera. Speed and accuracy are really important here.
As a sport shooter I will not miss a touchscreen, a turnable and swivable LCD, wifi,....
Low light possibility is a good step forwards compared to the old 7D. Even if it is quite the same sensor as the 70D. I have seen several pictures of a friend out of his 70D, and must honestly tell you I can't get them out of the 7D due to the noise. If even the noise of the 7D2 might be a little step better then the 70D, for instance caused by dual processor power, then also this would be a step forward. I agree, not as much as some expected, but you never can get the noise level of a FF out of an APS-C. Let that be clear. So all the wishful thinking of iso improvement of 2 or even more steps, or being better then a FF is impossible. The difference of noise level between a 70D and a Sony sensor is not that big, and is currently for sure actual.
So this sensor, combined with the other features, and for sure the new AF and the 10fps makes a great, challenging camera for the action shooter. I don't know yet anything about the new AF system performance, but I think that the 1Dx (better on low light) and the 7D2 (perhaps even better on tracking and focusing) might be real competitors. The only other performing camera in this area is the D4s according me. I'm curious to see the first previews of this camera. I'm also waiting to get the right € price and availability, because I want to exchange my 7D with this new action challenger quickly !!!
