In reply to ChrisJD:
Micro-adjustments are great because it saves the camera companies time and money calibrating it correctly in the first place :-P The only issue I have with it is that some lenses require different adjustments depending on focal distance and or focal length. It amazes me that no camera maker yet has auto calibration. It could use contrast detection AF to get a precise adjustment figure, then it would just save that for that particular lens. At least you should have the ability to enter a range of values on a sliding scale for zooms.
I gave up on Nikon because of phase detection AF issues (when the D800 and D4 came out and you had to be super super lucky to get a decent one) - the sooner PDAF is replaced the better
