The SB-12, the SB-16A, and the SB-17.....
And, with a TTL remote cord or the AS-7 shoe, different
ASA's can be set for the flash and camera, providing
TTL fill ratios.... (not bad, huh, for a "basic" flash
system? [though its slow sync. speed and 400 ASA top
film speed do favor using slow films with the F3 flash
system]).
Hope This Helps
