A Lens Types
When using a CPU lens equipped with an aperture ring ( 0 340), lock
the aperture ring at the minimum aperture (highest f-number). Type G
lenses are not equipped with an aperture ring.
Non-CPU lenses can only be used in exposure mode g (aperture-priority
auto) and h (manual). In other modes, exposure mode g is
automatically selected when a non-CPU lens is attached ( 0 342). The
exposure mode indicator ( e or f ) in the control panel will blink and F
will be displayed in the viewfinder.
