I have 24-70 and 70-200 zooms for my d600. No primes. Is there a preferred way to do this calibration with a zoom lens? Sorry if this was covered in the thread, but I didn't see it.

Thanks.

I would first tune at the various focal lengths of the zoom. Ideally they'll all tune within a few ticks of each other and you'll be done. However sometimes one end of the focal range will differ significantly from the other. For those cases you either have to average the two tune values (hopefully producing acceptable results for both) or pick a value closer to the one end you shoot at more often. Hopefully future Nikon bodies will implement dual-tune values for zooms like Canon did for the 5DM3/1DX/6D.
