In May 2000, Tamron introduced under the Bronica brand the RF645 rangefinder camera. Bronica later introduced optics and lens units of its own manufacture incorporating Seiko shutters with its later camera designs and held a portfolio of international patents.ДЄcquisition and product discontinuation Д«ronica was eventually acquired by the lens manufacturer Tamron Co., Ltd., in 1998 with emphasis on Bronica's optical lens manufacturing. Such was the design success of Bronica, that in the United States it attracted influential figures from the photographic industry such as Burt Keppler who met with Yoshino. The Bronica D was the Japanese answer and first serious challenger to the Swedish Hasselblad cameras, and in several technical ways outclassed the Swedish offerings. The Bronica Z modular camera system, shortly later with slight modifications renamed the Zenza Bronica D (Deluxe) and successor Bronicas, using large-coverage film format, high-quality Nikkor lenses supplied by the then Japan Optical Industries Co., Ltd., ( Nikon Corporation) became instant successes in the deluxe camera market worldwide.

The final prototype bore the Latinized nameplate 'ZENZA BRONICA'-the Bronica Z ( Zen-za) rollfilm camera-and first appeared at the Philadelphia Camera Show in March 1959, where it received ecstatic industry press coverage and left a deep lasting impression of being the world's dream camera. In June 1956 the Shinkodo Works created its first handmade example camera, and on reaching perfection in October 1958 with Yoshino's eighth prototype camera, the development costs had reached a sum of 200 million Yen, a huge sum at that time. The prototype was a modular camera named the 'Yoshino Flex'. On 17 January 1952, the Shinkodo Works was directed by Yoshino to begin research and development of the Bronica prototype camera. The Shinkodo Works was Yoshino's precursor production base and funding source for what would later serve his Bronica camera and photographic equipment manufacturing later consolidated under the Zenza Bronica Kogyo Kabushiki Kaisha (Zenza Bronica Industries, Inc) company. This formed the funding basis for his founding in 1947 of the Shinkodo Works with a vision of camera production, which at first produced Bronica brand luxury art deco accessories such as cigarette lighters and cases including watches, and positioned Bronica as a luxury brand in Japanese department stores, with popularity thriving among US Army soldiers in Japan. Yoshino's camera store and his immense familiarity with deluxe foreign cameras became a huge success with photography enthusiasts in Japan, buying and selling luxury Leica and Contax cameras, which also gained popularity with US Army soldiers stationed in Japan after World War II. Yoshino's ambition, however, would require substantial investment, which he gradually self-funded from his family business in transportation and his passion for cameras by the establishment of a small camera store in Tokyo's Kanda district.

Both fascinated and yet increasingly frustrated by the limitations of the cameras produced at that time period, where each camera's merits and demerits were not solved by just one camera, Yoshino visioned creating a high-precision interchangeable single-lens reflex camera modular system of his own design.

At an early age Yoshino showed deep reverence for the technical innovation and mechanics of world-renowned cameras produced by the likes of Leica, Contax and Rollei. 23 November 1988), wherefrom the Latinized Zenza Bronica brand name is derived, was the third son born into a Japanese rice merchant family.
