Aperture ring is selected, aperture can only be adjusted with
the lens aperture ring and the camera aperture display will
show aperture in increments of 1 EV (aperture for type G lenses
is still set using the sub-command dial). Live view is not
available when

an aperture ring is attached. Note that regardless of the
setting chosen, the aperture ring must be used to adjust
aperture when a non-CPU lens is attached.
