Nikon SB 12 (Used)

Designed exclusively for the Nikon F3 as a dedicated companion flash, the SB-12 Speedlight was Nikon’s first flash unit introduced with the Nikon F3 in 1980. It is a direct-mounting electronic flash unit providing automatic TTL control of the flash exposure. And It was also Nikon’s first flash to offer such a feature along with manual mode operation.
