Nikon S3M, April 1960
The first and only 1/2 frame camera ever produced by Nikon and highly source by collectors worldwide as it was known to be only 195 units being produced by Nikon thus far. It shares the same Nikon S3 chassis, but comes with a modified 72 exposures with format size of 18mm x 24mm and thus, the film counter has also been modified with 72 exp. Only available with cloth shutter curtain. Accepts the same motor drive like the SP & S3 for up to 6 fps (half frames) and most factory shipped cameras were supplied with the equally rare Nikon S72 Motor Drive. The same year, Nikon’s first Reflex Mirror lens, the Reflex Nikkor 1000mm f/6.3 for the Nikon-S series was produced.
