I've played around with the AF Fine Tune on the D3X with the 24-120 mm lens. It seems to be right on zero. Has anyone else had this experience?

"Played around" is perhaps not the right way to check as if the AF target is not good enough for reliable testing false readings can drive you nuts.
With over 25 lenses, 4 taking Nikon's TC's, all my lenses are accurate - with good AF targets. This fits in with Nikon's advice that fine tune is not normally needed.
I can make any of my lenses produce a front or back focus "effect" - by using the type of AF target Nikon say in the instructions for cameras with fine tune can allow a picture to be taken - despite the subject not being in focus.
This is caused by inappropriate AF target selection - something fine tune cannot correct.
Photography is a bit like archery. A technically better camera, lens or arrow may not hit the target as often as it could if the photographer or archer does not practice enough.
