But you should be aware that the Auto-focus Fine Tune option on Nikon camera bodies comes with some limitations for those of us who own third-party lenses. That limitation being only ONE third-party lens of a particular brand and only TWO brands of third-party lenses will be stored in-camera. For instance... If I have a Sigma lens, a Tamron lens and a Tokina lens I will only be able to store AF-Fine Tuning settings for two of them. If I add, say another Sigma lens, I'll have to choose *which* of the two Sigma lenses I want the camera body to store AF Fine Tuning information for because, once again... One lens per third-party brand, two third-party brands total. IMO, that sucks. By using the Sigma dock, and/or the Tamron Tap-in Console, the AF-Fine Tuning adjustments are made to the firmware of the lens itself; that information does not need to be stored on the camera body; which of course sidesteps the whole problem with Nikon not wanting to play nice with third-party glass. The other nice thing about the "dock" (or console) is that they allow you to adjust the auto-focus at multiple distances and focal lengths (for zoom lenses). My Sigma primes were all tuned at three different distances, and my Tamron zoom was tested/calibrated at four distances and three different focal lengths. Something no Nikon camera body will allow you to do.</blockquote>
