Just after started this series, my acquaintance Mr. X requested to take up this camera.
This camera, released in 1957, was equipped with a fisheye lens that was the ancestor of later Fisheye Nikkor and used 120 (6 x 6 cm) format film, one of very few example among Nikon Cameras. In that sense, it was a very interesting camera, but I gave up to take it up because there was too little material.
In this series, I try to include the fact which cannot be got through the study of written records only. It was easy to include such facts if I myself was engaged in the development or, otherwise, I was in a position to obtain the information in the period when the development was proceeding, but in other cases, especially about the products of the time before I joined the company, I had to interview seniors who actually took part in the development in order to get such information. However, I couldn't trace such seniors regarding this "Fisheye Camera".
But I could look into the prototype. The camera itself was very simple, and the film winding stopper mechanism, for instance, was very smartly designed.
It was mentioned about this camera including the circumstances of the development in "Digital Archives" in this web page, please refer to that.
