Nikon f2 - Manual (Page 52)

The Nikon F2SB Photomic camera is designed to syn­
chronize with most types of flashbulbs at almost all
shutter speeds and with electronic flash at speeds to 1 /80
second. The table below shows which shutter speeds
may be used with different types of flashbulbs.

No special adapters are necessary when using the Nikon
F2SB Photomic camera with the Flash Unit BC-7 or
with the Speedlight Unit SB-2. Both units mount direct­
ly on the camera’s accessory shoe and they require no
sync cords. For other flash units with ISO-type hot-shoe
contacts, mounting on the camera is via the Flash Unit
Coupler AS-1; again no sync cord is required, as the
AS-1 provides full connection via the camera’s hot-shoe
contact.
Caution: When the reflex mirror is locked in the up position,
the shutter will not synchronize with flashbulbs at speeds faster
than 1 /80 second.
