Nikon FG Instruction Manual page 19

The lenses usable for the Nikon FG are all the AI-type
Nikon/Nikkor lenses, including most of the AI con-
verted lenses, certain Reflex Nikkor and PC Nikkor
lenses. Non-AI Nikkor lenses and lenses of other
manufacturers which do not have the AI feature must
not be forcibly mounted on the FG. Attempts to mount
such lenses will damage the camera's indexing
mechanism. Note that in addition to non-AI lenses
the following lenses cannot be used: '

Focusing Unit AU-1
When using the Teleconverter
TC·200, TC·201, TC·301 or
TC·14A
Exposure compensation, which is required
when using Nikon AI-type cameras with lenses
having a maximum aperture faster than f/2 or
faster than f/1.8 (when using the TC-14A), is
not necessary when using the FG in its P or A
mode. In the A mode, however, note that the
actual shutter speed will be faster than that
indicated in the viewfinder by less than one
step. Therefore, before shooting, be sure that
the shutter speed LED(s) in the viewfinder
indicates a speed slower than 1/250 sec. In
the manual mode, exposure compensation
using the ASA/ISO film speed dial is necessary.
See the teleconverter's instruction manual for
complete details.
