If you read reviews, it is clear that Nikon's more recent AF implementations (e.g. D810, D750) are superior - especially in acquiring and tracking moving subjects with the help of color information.
A few weeks ago a friend and I swapped rigs for part of a birding shoot (eagles and owls) – his D810 and 800/5.6 for my 1D X and 600/4 II + 1.4x. While both bodies did an excellent job at initial acquisition (both of brown eagles against a green background and snowy owls against snow), we agreed that the 1D X did better at maintaining the lock (even with the TC).
Nice anecdote. How about you actually do some repeatable testing where you take out all the random crap like how subject moves, how well the photographer is able to keep focus points on right spot on the subject and light conditions, and perform the test repeatedly over a variation in all relevant autofocus parameters. Then your opinion could actually hold some weight instead of being considered the usual worthless internet garbage.
You mean like Tony Nothrup's conclusion that the D810 was a better sports camera than the 5D3? Tests like that? I'm sure that test took into consideration, whole-heartedly, the considerations you mention.
Got anything better to contribute than some lame strawman argument? If not it is better to not post at all.
Neuro's anecdote is worth more than the vague 'X is better than Y' it was countering, which offered no supporting evidence. Rigorous, controlled tests are much better of course, but nobody is arguing against that. Can you point us to some?
For distance tracking, ie photographer keeping a focus point on the subject then I have not seen any proper controlled tests. I would love to see it if someone has done it however. In the absence of such test, arguing that system X is better than system Y has no value.
When it comes to subject tracking DPReviews videos clearly demonstrate that Canon is far behind as it is almost useless while on Nikon or Sony it can actually be useful and more practical than manually changing focus point.
Wrong again. If you set it up properly, the 1Dx auto-switch point for tracking works just fine. I know because I do it. But hey, you watched a video, so that must be better! The internet said so!
Maybe you can make a video to demonstrate how you successfully track the eye of your subject as it moves across the frame then, like DPReview did with the D750?
