Zenza Bronica camera which was released in March 1959 was organized by Zenzaburo Yoshino. To make his ideal camera, he spent his private money of over 100 thousand yen and over 8 years though he was not a professional camera designer. After world war II, he managed a company which made cigarette case, oil lighter and women's compact, and also had his own camera shop in Tokyo because he was a very enthusiast of camera. However, he was not satisfied and started a plan to make a world's best camera by himself. Then finally, he had achieved his dream after putting a lot of his time and expense. The first Zenza Bronica released at that time is 6x6cm focal-plane single-lens reflex camera which is similar to Hasselbrad regarding its style and size, but this camera has various advantages that feature is not equipped on not only hassy on the day but also the existent one: 1) after taking, the mirror and aperture are returned to the original position, 2) to keep the optical back of the lens, the mirror is not flipped-up but slided-down 3) very long exposure up to 10sec using self-timer 4) the film back can be attached without regarding both body/back sequences 5) the film can be loaded fully automatically as Rolleiflex without adjusting the start mark. Consequently, it had already satisfied the all basic requirements for SLR cameras, and it is also an admirable advanced one with considering the release of Nikon F in June of this year. Furthermore, it must be noted that the camera is the most small and light-weighted one in the all Zenza Bronica with a focal-plane shutter and has a very elegant and delicate exterior design. Originally, that first camera was called "Zenza Bronica" and then renamed "Zenza Bronica type D (deluxe)" when the next "type S (standard)" debuted for identification. They say that the name "Zenza Bronica" was came from "Zenzaburo", "Brownie" and "Camera". Even at the beginning, Nikkor lenses, 5cmF3.5, 7.5cmF2.8 and 13.5cmF3.5 are equipped to the camera. Of course, Mr. Zenzaburo Yoshino selected Nikkor because he thought that the best lenses must be equipped to the best cameras, Actually, it is easily lead from the history of Zenza Bronica, they could not make lenses by themselves. But Nikon F and its system introduced in the same year is very popular and they could not supply enough lenses for Bronica. For that reason, Zenza Bronica Industories inc. got into the technology of design and manufacturing lenses, and replaced the lenses to their own made. Consequently, 6x4.5cm format leaf-shutter camera (Zenza Bronica ETR) never adopted Nikkor lenses.
