And that is what you call full feature?  :blink:

 

How much sense would it make for Nikon to limit the number or properties of focus points to Nikon only? I expect, if a focus point can be chosen, it will work properly - everything else is attempt of betrayal, no? :ph34r:

 

Also, if Nikon is picky for their own lenses as to which points can be used with which Nikkor, you hardly can expect them to treat the competition better - on one side. And on the other side, even as a "Nikkor and nothing else"-fanboy one doesn't get full access to all points - so what's the real benefit of going the Nikon only path?  ^_^

 

 

  I don't know if Nikon's picky-ness is due rather to "technical difficulties" aperture sizes and light, for example the G2 on the D500 can't focus to the extreme high corners of the array at 600mm, but will at 500mm (not with a cross point) , oblique light at smaller apertures prevents it. 

 

  What's the real benefit of using Nikon glass?   Well at least you know that they were designed for Nikon cameras by Nikon, and not reversed engineered to fit Nikon and your getting the maximum AF performance out of your DSLR. 

 

  But then my favourite lens is the G2, it nails AF......and on any Nikon I've put it on.....AFFT always seems to be -2.
