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. 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.
