Auto AF Fine-Tuning
The D850 can fine-tune autofocus automatically. The re-
sults can be used with all lenses of the same type.
Use only as required. AF fine-tuning should be performed at
the focus distance at which the lens is normally used; fine-
tuning performed at short focus distances may be less effec-
tive with distant subjects and vice versa.
Ready the camera.

Mount the camera on a tripod and aim the camera at
a flat, high-contrast subject parallel to the camera fo-
cal plane. Note that auto AF fine-tuning works best
at maximum aperture and may not function in dark
surroundings.
