AF claimed to work down to EV -2, one stop darker than the 1D IV
And 1 stop more at the other end. Should be excellent in low light, addressing the one criticism of the 1D IV.
Well, Pixie, it is much more than that. One stop increase in AF point light sensitivity means a significant boost in AF response with all lenses, at most of practically encountered light levels.
With 1DX, your 500 f/4 should now AF very similarly to your 300 f/2.8 IS.
A lens with a huge defocus range such as 800L, should also become more AF agile on 1DX.
The incidence of focus search initiation will be reduced. That way the user should experience less \"lens hunting\" and faster lens AF move in initial acquisition.
All that ought to translate more readily is an improved keeper rate.
Now, what remains is to see what out friend Rob Galbraith has to say about the \"proof of the pudding\".
