Lens Types
When using a CPU lens equipped with an aperture ring (
0
320), lock
the aperture ring at the minimum aperture (highest f-number). Type G
and E lenses are not equipped with an aperture ring.
When using non-CPU lenses ( 0 163), select exposure mode
A
or
M
and
adjust aperture using the lens aperture ring. If exposure mode
P
or
S
is
selected with a non-CPU lens, the camera will function in exposure
mode
A and

will appear in the viewfinder. See page 318 for more
information.
A Non-CPU Lenses (
0
163)
Use the lens aperture ring to adjust aperture.
If the maximum aperture of the lens has been
specified using the
Non-CPU lens data
item
in setup menu (
0
163) when a non-CPU lens
is attached, the current f-number will be
displayed in the viewfinder and control panel,
rounded to the nearest full stop. Otherwise
the aperture displays will show only the number of stops (
F
, with
maximum aperture displayed as
F A
) and the f-number must be read
from the lens aperture ring. Aperture for lenses not equipped with AI
mechanisms (non-AI lenses) is adjusted using the lens aperture ring.
Changes to aperture are not shown in the camera displays; use the sub-
command dial to set the camera to the aperture selected with the
aperture ring (
0
168).
