Nikon Nikkor-D 1:4 f=40mm for Bronica 6x6

This is the widest production lens that Nikon made for Bronica S, S2 & S2A cameras, with an angle of view wider than a 24mm lens in 135 format. The lens is relatively compact except for the front which flares out to accept massive 90mm filters. It appears to have been multi-coated from the beginning as there is no "ĚC" version to distinguish it from a single-coated version.
  • First lenses are marked "Nippon Kogaku Japan".
  • Most are marked "Nikon", but otherwise the same as before.
