Af Fine-Tune - Nikon D850 Menu Manual

AF Fine-Tune

Fine-tune focus for up to 20 lens types. Use only as required; AF
tuning is not recommended in most situations and may interfere
with normal focus. Auto fine-tuning is available in live view
(0 166). We recommend that you perform fine-tuning at a focus
distance you use frequently; if you perform focus-tuning at a
short focus distance, for example, you may find it less effective at
longer distances.
