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- lyon 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-'; again no sync cord is required, as the AS-' provides fu II 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 flashbu lbs at speeds faster than 1/80 second.
