Non-CPU Lens Data
Specifying the focal length and maximum aperture of non-CPU lenses
using the Non-CPU lens data option in the setup menu (0 218)
allows the camera to use color matrix metering when matrix is selected
and improves the accuracy of center-weighted and spot metering.
Center-weighted metering will be used if highlight-weighted metering
is selected with non-CPU lenses or if matrix metering is selected with
non-CPU lenses for which lens data have not been supplied. Note that
center-weighted metering may also be used if highlight-weighted
metering is selected with certain CPU lenses (AI-P NIKKOR lenses and
AF lenses that are not of type G, E, or D; 0 284).
