Few people have heard about the Zunow camera. Even fewer have seen photographs of it, and fewer still have actually seen one live. The number of people owing one is probably so low that even collectors have given up finding one. It was produced in very
low numbers in Japan from 1958 and for only a short time. A production rate of only 8 pieces a day was not enough to pay for the expenses. Besides, it was only sold in Japan. Probably less than 500 were produced from August '58 till end of production in '59.
The camera was ahead of its time, with some worlds first features, like the auto diaphragm technique. (Well, hungarian Gamma Duflex had it some ten years before, but that was a porro prism, not a penta prism.) But although the cameras were on a high technical
level, the quality was not quite matching. They needed to be often serviced, at least once a year when regularly used.
Zunow Optical Company started producing lenses for other brands early in the 40's, and with great technical success. Later,
rangefinder cameras like Leica and Nikon were among the ones to gain from this, although they made first class lenses themselves. Zunow made 1:1,1 lenses when others struggled with 1:1,8!
The very first Orion/Mirandas also came with Zunow lenses.
After ending the camera production, Zunow went back to producing lenses, until financial problems forced them to give up in the early 60's.
