ACCESSORIES ^continued
Close-up equipment
The following are some of the accessories you can use for
close-up photography.
1) Close-Up Lenses No. 0, No. 1, No. 2, No. 3T, No. 4T, No. 5T,
No. 6T.
Since these lenses are attached to the front of the lens in
use, metering can still be done at full aperture.
2) Auto Extension Rings PK-11A, 12 and 13.
3) Bellows Focusing Attachment PB-6.
The Auto Extension Rings and the PB-6 are attached between
the lens and camera body. If one of the rings is used with an
Al lens, exposure determination is at full aperture because
the exposure meter is linked to the automatic diaphragm of
the lens. As for the PB-6, stop-down exposure measurement
is necessary because the exposure meter is not linked with
the automatic diaphragm of the lens. You can change magni­
fications continuously by extending the bellows.
Note, too, that it is possible to use a close-up lens, ring and
the PB-6 all at the same time.
4) Micro-Nikkor 55mm f/2.8, Micro-Nikkor 105mm f/2.8, Micro-
Nikkor 200mm f/4, AF Micro-Nikkor 60mm f/2.8 D, AF Micro-
Nikkor 105mm f/2.8 D and AF Micro-Nikkor ED 200mm f/4 D
IF lenses. These specially designed lenses for close-up pho­
tography offer continuous focusing from infinity down to 1/2
(Micro-Nikkor lenses) or 1/1 lifesize (AF Micro-Nikkor lenses).
The closest focused distance of the lenses are 0.25m (0.82
ft.), 0.23m (0.75 ft.), 0.41m (1.34 ft.), 0.219m (0.719 ft.),
0.314m (1.03 ft.) and 0.5m (1.64 ft.), respectively.
Note that in close-up photography, the depth of field is generally shallow.
Thus, you should stop down as much as possible in photographing a subject
with very little depth. Also, it is advisable to use the Type K2's matte outer
field for focusing (or to change focusing screens) because it is no easy to
focus with the split-image or microprism ring,
