A camera designer's dream realized a fixed-zoom lens camera
AF(Autofocus) point-and-shoot compact cameras with zoom lenses, some of which are small enough to hold in a pocket, sell very well.
This had been a camera designer's dream for a long time cameras with fixed zoom lenses that didn't require switching lenses with various focal length.
The NIKKOREX Zoom 35, marketed in 1963, was the first camera which realized this dream more than 30 years ago.
Zoom lenses had long been developed for movie cameras. before 1959, when the "Voigtländer-Zoomar 1:2.8 f=36mm...86mm" was adopted as an interchangeable lens for the lens shutter SLR "Bessamtic" of the Voigtländer, Germany.
This was the first time a zoom lens was used for a still camera.
In December the same year, Nippon Kogaku K.K. marketed the Auto Nikkor Telephoto Zoom 85mm f/4 - 250mm f/4.5 lens for the Nikon F.
Various focal lengths were obtainable using this single lens, freeing photographers from having to switch lenses frequently.
Such utility was welcomed by valious camera users.
Thus the "age of zoom lenses" started in the still camera world.
If a single zoom lens can cover the normal shooting range of focal lengths, photographers no longer have to change lenses.
Then, interchangeable lenses no longer have to be interchangeable and can be fixed to camera bodies.
With this camera having a zoom lens fixed to its body, you can enjoy various frame angles economically.
On the other hand telephoto and wideangle front conversion lenses were prepared for the NIKKOREX 35 (1960) and NIKKOREX 35II (35/2) (1962) (See "Nikon Family Cousins: Part 1"), lens-shutter SLR cameras having no lens-interchangeability.
These front conversion lenses were, however, too large to be used easily and were awkward to handle.
Nippon Kogaku K.K. designers thought that telephoto and wideangle effects should be easier to attain, in order to take full advantage of the NIKKOREX as an SLR camera. These led to development of the NIKKOREX Zoom 35.
