Nikon S (Stereo-Nikkor 3.5/3.5cm, S or S2)

The Nikon S (Stereo-Nikkor 3.5/3.5cm) represents an interesting chapter in Nikon's early development as they established their presence in the photographic market following World War II. This specialized 35mm stereo camera was designed to capture two slightly offset images simultaneously, creating stereoscopic photographs that could be viewed with special equipment to produce a three-dimensional effect. The dual 35mm lenses with f/3.5 apertures were precision elements that would have demonstrated Nikon's growing optical expertise, a skill they would later perfect in more famous products. The camera body likely followed the sturdy, functional design principles characteristic of early Japanese cameras, built for reliability rather than elaborate aesthetics. While not among Nikon's most celebrated models, this stereo variant shows the company's experimentation with different photographic formats during the formative years before their landmark F camera in 1959.

Stereo photography enjoyed a dedicated but limited market during the 1950s, appealing primarily to enthusiasts and professionals interested in creating three-dimensional images. The Nikon S operated on 135 film (the standard 35mm format), which made it more accessible than bulkier stereo cameras using larger formats. This specialized nature meant it never achieved widespread popularity, but the camera demonstrated Nikon's capability to engineer complex optical systems with precision alignment. As one of the first dedicated stereo offerings from what would become a photographic giant, the Nikon S represents an important step in the company's evolution toward their more iconic products that would soon revolutionize photography.
