My D7000 can't hit a cows rear end with a Banjo..AF is all over the place

Thanks!

I believe 9 point x-type with center point being capable to f2.8

This is not correct.  All 9 points are cross type sensitive, sensitive to both horizontal and vertical lines, for lenses with a maximum aperture of f/5.6 or faster. The center point will focus 3 times more accurately with a f/2.8 lens than with an f/5.6 maximum aperture lens such as the 18-55 at 55mm.

The outer 8 points are still cross type sensitive with a f/4, f/2.8, f/2, or f/1.4 lens.


Isn't that without the details what I said?

No, it's fundamentally different. You said the center being cross type sensitive to f/2.8 but said nothing about it being 3 times more accurate with an f/2.8 or faster lens.  That is the whole point of having a f/2.8 cross type autofocus point.
