Nikon FG Instruction Manual page 63

The camera body
yo~
purchased is packaged separately from the
lens. Before mounting the lens, check if it is capable of Automatic
Maximum Aperture Indexing (AI) operation with your camera body
by verifying that the lens' aperture ring is fitted with a meter cou-
pling ridge as illustrated at the right.
If the lens is fitted with the meter coupling ridge, it is capable of
full-aperture exposure measurement; to attach it to the camera,
follow the directions provided in the Basic Operation section of this
instruction manual. If the lens is non-AI, it cannot be mounted on the
Nikon FG. For further details on usable lenses and their recom-
mended modes, please refer to pages 19 and 27.
Note: AI-conversion of most non-AI Nikkor lenses having both an automatic
diaphragm and meter coupling prong is available at reasonable cost for the
convenience of Nikkor lens users. Please contact your local authorized
Nikon dealer.
