Let me break it down to ya before we start calling people ignorant.

If a zoom is front/ back focused on one end but not on the other, what happens if you AF tune ?

Give up?  If you guessed the AF tune will fix one end but mess up the other, you guess correct!

So AF tune will improve accuracy on one end, but will have negative effects on the other end.

If you haven't noticed the D800 AF tune effects the ENTIRE lens.  It works great on primes, but not on Zooms.

So ya... am I missing something here?
