Nikon Z9 Mirrorless Camera - Manual (Page 718)

718 B The Setup Menu: Camera Setup
Record data for non-CPU lenses attached using an optional mount
adapter. Recording the focal length and maximum aperture of non-CPU
lenses allows them to be used with some camera features normally
reserved for CPU lenses, such as on-board vibration reduction.
When [ ON ] is selected, the camera will save the current focus position
when turned off and restore it when next turned on. Note that this
increases camera startup times.
• Note that even when [ ON ] is selected, if the temperature, zoom
position, or other conditions change while the camera is off, focus
may resume from a different position when the camera is turned on.
• Similarly, note that even when [ OFF ] is selected, focus may resume
from the previously-selected position depending on the state of the
camera and lens.
