APERTURE The lens aperture ring setting, of f: stop, depends
on light conditions. The exposure guide packed with your
film tells you the correct f: stop.
Note; The largeSi" f: stop is f: 1.4 and the smallest f: stop is
f: 16, the highest number on the lens aperture ring.
FOCUSING The focusing ring permits you to adjust the
lens for any subject distance. If you sel' it to 4, objects 4
feet away will be sharp. But objects closer and farther than
4 feet will also be sharp. For example, at an aperture of
f:8, everything between 2 feet arId infinity (very far Qway)
will be reasonably sharp. If, because of dim light, you open
the lens aperture to f:4, the sharpness zone would be from
about 2t feet to 10 feet.
Here is a focus rule of thum b for most accassions:
If your subject is nearby, set focusing ring at 4.
If your subject is far away set it to 20.
Be sure to consult the depth-of-fleld table on page 13 to
gain a more complete idea of zone-of-sharpness.
THE D-~OUNT

D-mount and is._ designed to international standards. There-

position, the bottom, the standby position.
To use the standby lens, grasp both
lenses and rotate the turret until the
