Nikon BC-5 Flash Unit with Nikon F adapter and leather case.


The BC-5 is the flash bulb unit that couples directly to the S2, S3, S4 and SP rangefinder cameras. The adapter lets you use it on the Nikon F and F2 SLRs.


Or, in Nikon Speak...

“The Nikon BC-5 Flash Unit makes perfect electrical connection with the flash terminal, on the Nikon camera only, by sliding directly (in the Nikon model S2, S3, S4, SP) or by aid of an adapter (in the Nikon model F) into the camera’s accessory shoe, eliminating the need for a connecting cord.”


Some signs of use on the base, slight marks on the face plate, otherwise in excellent condition with the caveat that, while I have an S2, I don’t have a stash of flash bulbs or batteries needed to test the thing. Nikon S2 NOT included.
