Close-Up Equipment
For shooting subjects which are iocated cioser than the ciosest
possibie focusing distance of the iens, Nikon makes a wide
variety of equipment:
1) Cióse- Up Attachment Lenses Nos. 0,1,2, 3T, 4T, 5T, and 6T.
These ienses screw into the front of the iens just iike fiiters
to magnify the image. Exposure metering can stiii be done at
fuil aperture without compensation.
2) Auto Extension Rings PK-11, PK-12, PK-13.
These fit between the iens and camera body. Used singiy or
in combination, exposure determination is done at fuii aper­
ture with ail Al-type lenses. (The PK-11 cannot be attached to
the AF-Nikkor lenses.)
3) Bellows Focusing Attachment PB-6.
The PB-6 is also attached between the lens and camera body.
Exposure is determined by the stop-down method. The
beauty of this accessory is that you can change magnifi­
cations continuously by extending the bellows.
4) Micro-Nikkor 55mmf/2.8,105mm f/4, and 200mm f/4 IF.
These specially designed lenses offer continuous focusing
from infinity down to 1/2X lifesize. To obtain 1/2X to IX mag­
nification with an Al Micro-Nikkor lens, the use of an auto
extension ring is required: the PK-13 for the 55mm f/2.8, and
the PN-11 for the 105mm f/4; to obtain magnifications from
infinity up to IX with the 200mm f/4 IF, use the Nikon Tele­
converter TC-300. Even with these accessories, exposure is
determined at full aperture. Note that in close-up photography,
depth of field is generally shallow. Thus, you should stop down
as much as possible when photographing a subject with great
depth. Since Micro-Nikkor lenses are not compatible with the
F3AF's autofocus and focus-aid functions, focusing must be
done by manually rotating the focusing ring ®) while using the
matte portion of the DX-l’s focusing screen. For critical
