Other than that I was abysmally disappointed. It was too slow in every respect, including AF. I often found that it had a tough time keeping up with subjects moving toward and away from the camera. The 7d2 has a much faster AF system but is overshadowed by the amazing 1dx2.
What do you mean by 'slow'? There are two aspects IME that are rarely distinguished:
- response time to capture the moment
speed for tracking focus
As an example, one of my obsessions at the moment is the local kingfisher and I realised that I am less interested in capturing it in flight and more interested in capturing the dive and it hitting the water.
The latter needs quick reactions by me (and the camera) when I see it diving and about to hit the water, the former relies on tracking which is a different skill.
Also I can imagine that if you are into animal behaviour pretty much the same thing applies to catch an interesting moment.
Having used 7D, 7DII 5D, 5DII, 5DIII, 1DsIII, 1DIV, 1DX, 1DXII and 5DSR extensively, I find it difficult to comprehend your "abysmally disappointed". As many have pointed out, including Grant in his review, you have to pay attention to your technique, to really benefit from the high resolution and there is an ISO limit. In general I lose one stop, due to a faster shutter speed and yes, the 1DX and especially the 1DX-II has a better AF system and a much higher fps. But compared to the other cameras listed above, the 5DSR equals or beat them (except for 1DIV and 7DII with regards to fps).
So if your problems were for real, they must have been caused by one of two; Either finger trouble on your end or a faulty camera. My 7DII works well and I am happy with the AF system, but the 5DSR is better. The 5DSR is also better than the 5DIII. Besides Grants excellent review, you can also check out Art Morris. I believe their images of both wildlife and birds (also in flight) are proof good enough.
Mikehit; For your Kingfisher dives, I would rather recommend a 7DII (or preferably a 1DX or 1DXII), due to the fps performance.
