Nikon Speedlight SB-4

Introduced in 1977, the SB-4 was the first small flash unit produced by Nikon with automatic flash control. It has a foot that attaches to cameras with a standard flash shoe, such as the Nikon F and F2, the Nikonos II and III, and the Nikkormat EL, FT2, FTn, FT, and FS. It was also intended for use in still-frame mode with the Nikon R8 and R10 Super 8 movie cameras.
