Aperture
Shutter speed
When a CPU Nikkor lens other than G-type is not set to its minimum aperture
setting, ƒEE blinks in the top LCD panel and viewfinder and the shutter locks.
When a non-CPU lens is attached, the exposure mode automatically switches to
Aperture-Priority Auto, ¡ blinks in the top LCD panel and £ appears in the
viewfinder. When the maximum aperture is specified in “Non-CPU lens data” (x
144), aperture value is displayed in the top LCD panel, rear LCD panel (in detailed
or large display) and viewfinder. In this case, aperture can be set to intermediate
values with the aperture ring but the display only shows changes in one EV steps.
When the maximum aperture is not specified, the aperture display shows the EV
step difference from the maximum aperture (i.e., ∂2: two steps from the
maximum aperture); set/confirm aperture with the lens aperture ring.
When the subject is too dark or bright, one of the following warning indications
will appear in the top and rear LCD panels (detailed and large displays) or
viewfinder:
H1: Use ND filter.
Lo: Use Speedlight.
