At roughly the same time Nikon was revolutionizing the world of 35mm photography with the introduction of the Nikon F (1959) they were also experimenting with other SLR designs to sell to eager photographers. In 1960 they launched the Nikkorex line of 35mm SLR cameras targeted toward more economically-minded users. These cameras had non-interchangeable Nikkor lenses, lighter weight porro prism finders and non-TTL selenium light meters. Only a few models were produced with the Nikkorex Auto 35 (1964) being the last of the line before this family of cameras gave way to the Nikkormat series.
The Nikkorex Auto 35 incorporated a more modern look and feel to its design over its predecessors, using nicely rounded contours, recessed rewind crank and advance lever, and sporting a fast 48mm f2 lens. The Nikkorex Auto 35 was also the first Nikon camera to feature shutter priority automatic exposure, giving the camera the "Auto" in its name. The leaf shutter was manually set between speeds of 1 second to 1/500 (plus Bulb) and then the aperture could either also be manually set between f2 to f16, or the camera had an additional "A" setting in which case the selenium meter took over and chose the correct aperture for the selected shutter speed. This was a pretty nifty innovation for the time and particularly attractive for the more amateur user who didn't necessarily feel comfortable metering on their own.
Of the entire Nikkorex line, we daresay this might be the nicest of the bunch!
