Flash photography

A Nikon electronic flash unit will prove very convenient for indoor or nighttime shooting or for use in the daytime as sup- plementary lighting . The FM2'sbuilt-in hot-shoe contact @ enables direct mounting of the Nikon S8-27, S8-26, S8-25, S8-24, S8-22, S8-20, S8-19 or S8-168 Speedlight, requiring no special connecting cords. When shooting with a flash unit, you should determine the aperture setting that corresponds to the shooting distance after checking the guide number of the electronic flash unit or flashbulb in use. Also, if the speedlight requires the use of a connecting cord, insert the cord into the camera body'ssync cord terminal @. Since the FM2'shot- shoe contact becomes active only when an electronic flash unit is mounted, touching it accidentally is harmless.

The use of flash units not provided with a hot-shoe contact'is not recommended because accidental firing is likely to occur due to short circuiting at the contact. When using such flash units, seal the hot-shoe contact on the camera body with vinyl tape or something appropriate to insulate it.

The FM2, provided only with an X-contact for synchronization, synchronizes with the speedlight when the shutter speed set is 1/250 sec. or slower.
