Nikon Camera F3AF - Manual (Page 127)

IMPORTANT!
The Nikon F3AF is an Al-type (Automatic Maximum Aperture Indexing) camera
which performs full-aperture metering with Al-type lenses. The aperture ring of
these lenses has a meter coupling ridge ® and a meter coupling shoe i@ containing
two holes (see illustration). Almost all lenses now manufactured by Nikon are ot the
Al type. Flowever, please confirm whether or not your lens is Al before using it with
the F3AF. Note that the "Al” or "Al-S” mark on the cover of the instruction sheet
or book provided with Al-Nikkor lenses is your assurance that the lens offers the Al
feature. All Nikon Series E lenses have the Al feature but do not have a meter
coupling shoe.
To attach an Al-type lens to the camera body, follow the directions provided in the
BASIC OPERATION section of this instruction manual. If the lens in a non-AI type,
stop-down exposure measurement is required with the camera body's meter
coupling lever ® locked up (refer to the page 41).
Note: The modification, at reasonable cost, of most non-AI Nikkor lenses having both an auto­
matic diaphragm and meter coupling shoe, is available for the convenience of Nikkor lens
users. For further information concerning lens modification, please contact your local author­
ized Nikon dealer.
