Bronica also Zenza Bronica (in Japanese: ゼンザブロニカ) was a Japanese manufacturer of classic medium-format roll film cameras and photographic equipment based in Tokyo, Japan. Their single-lens reflex (SLR) system-cameras competed with Pentax, Hasselblad, Mamiya and others in the medium-format camera market.

History

Before introduction of the first of what would become a dynasty of Zenza Bronica cameras in 1959, the Latinized Zenza Bronica name was already a popular Japanese luxury goods brand of the Shinkodo Works (in Japanese: 新光堂製作所) since 1947,[1] specialized in the production of intricate crafted and decorated personal accessories, such as metal cigarette lighters[2] and cases, cosmetic compacts, and watches,[3]

Film camera production

The prototype was a modular camera named the "Yoshino Flex". 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,[1] the development costs had reached a sum of 200 million Yen, a huge sum at that time. 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.[1] The Bronica Z modular camera system, shortly later with slight modifications renamed the Zenza Bronica D (Deluxe)[6][7] and successor Bronicas, using large-coverage film format, high-quality Nikkor lenses supplied by the then Japan Optical Industries Co., Ltd.,[4] (Nikon Corporation) became instant successes in the deluxe camera market worldwide. 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.[8] 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. 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.

Acquisition and product discontinuation

Bronica was eventually acquired by the lens manufacturer Tamron Co., Ltd., in 1998 with emphasis on Bronica's optical lens manufacturing. In May 2000, Tamron introduced under the Bronica brand the RF645 rangefinder camera.[6] Tamron discontinued the brand's single-lens reflex camera models (ETRSi, SQ-Ai, SQ-B and GS-1) between June 2002 and December 2004,[9] sales having suffered from the lack of consideration to a digital camera back and loss of market share to digital photography and digital single-lens reflex (DSLR) cameras, particularly for the wedding and portrait photography business which had previously been a heavy user of medium-format photographic film but switched quickly to digital photography for its commercial workflow benefits.[7][10] Bronica's last model, the RF645 rangefinder camera, was discontinued in September 2005, and marked the termination of the Bronica camera brand business.

JCII camera museum

The Japan Camera and Optical Instruments Inspection and Testing Institute (JCII) at its camera museum located in Ichibanchō district, central Tokyo, has a selection of Bronica camera models preserved among its museum display collections; as part of the museum's designation "preserving cameras considered of historical significance".[11]

Bronica models

Bronica SLR system-cameras employed a modular design: The major components of the camera—lens, body, film-back and viewfinder were separate and interchangeable, providing options to match the specific photography or workflow needs of the photographer.

Classic models

From its start, Bronica introduced a number of 6x6 cm medium-format SLR cameras with focal plane shutter, which used Nikkor lenses from Nikon,[4] until this line was discontinued with the introduction of the successor Bronica SQ-series. These models included:

Notably, the Bronica EC was the first medium-format SLR camera with an electrically operated focal plane shutter (Japan Patent No.: 43/94431 24 December 1968; US Patent No. US3696727[12]), while the EC-TL was the first medium-format camera with Aperture priority automatic exposure (AE).

The range of Nikkor lenses for these remarkable cameras reached from 30mm (fisheye) to 1200mm and comprised about 30 lenses. Lens optics supplied by Carl Zeiss in Jena, Tokyo Optical Co., Ltd., Norita optics, Komura-Komuranon (Sankyo Kohki), Schneider Kreuznach, as well as lens optics later manufactured by Bronica itself (Zenzanon) based on designs by Zeiss and Japanese lens manufacturers were available, as well as a wide range of accessories, including different film magazines, bellows, and viewfinders.

Bronica Z (Zen-za), debuted March 1959 at the Philadelphia Camera Show and renamed Bronica D (Deluxe) in December 1959[6] with slight modifications; production discontinued March 1961[9]
Bronica S (Standard), introduced April 1961;[6] production discontinued April 1965[9]
Bronica C (Compact), introduced December 1964;[6] production discontinued May 1965[9]
Bronica C2, introduced May 1965;[6]

ETR series

ETR: Introduced March 1976,[6] production discontinued March 1980.[9] Advanced, compact, modular electronic 6x4.5 cm medium-format SLR camera system with a vast array of finders, film-backs, and other accessories. ETR was an acronym for Electronic, TTL-metering, Reflex. In 1977 the ETR received Japan's Good Design Award. Seventeen lenses with leaf shutters were made for the ETR-system from a fisheye, to four different zooms, to a 500mm super telephoto, to a unique 55mm tilt shift lens.
ETR-C: Introduced November 1977,[6] production discontinued December 1980.[9] Identical to the ETR model except film magazine cannot be removed from film-back.
ETRS: Introduced October 1978.[6]

SQ series

SQ: Introduced August 1980[6] as replacement and successor to Bronica's classic and increasingly bulky Nikkor-lens based cameras, production discontinued September 1984.[9] Modular 6x6 cm traditional "square film" medium-format SLR camera system with leaf shutter lenses.
SQ-A: Introduced January 1982,[6] production discontinued December 1991.[9] The SQ-A was a refinement of the SQ. The contact pin array for the viewfinder was increased from six to ten gold contacts, allowing for auto metering capability with the AE finder S. Also, a mirror lock-up lever was added. The film-backs were modified slightly, with the ISO dial for the original film-backs having white and orange numerals, and the new with silver. The darkslide was changed to the locking style; to lock required both the new grey handle slide and the new silver numeral ISO dial back. All accessories for SQ cameras fit the SQ-A, however the AE finder cannot physically mount on the SQ; a safety defeat pin prevents attachment.

GS series

GS-1: Introduced April 1983,[6] production discontinued June 2002.[9] Lightweight, electronically controlled, modular 6x7 cm medium-format SLR camera system with leaf shutter lenses, four interchangeable viewfinders, speed grip, and optional film-backs for Polaroid Land pack film, 6x4.5 cm, 6x6 cm, and 6x7 cm rollfilm. 120 and 220 size film-backs available in 6x4.5, 6x6 and 6x7 cm. A 35mm film-back was listed in the camera's marketing materials, but never materialized. Dedicated Flash (G1). The GS-1 uses "PG"-series lenses in a variety of focal lengths: 50mm, 65mm, 80mm, 100mm, 110mm macro, 150mm, 200mm, 250mm, and 500mm.

RF series

RF645: Introduced May 2000, production discontinued September 2005.[7] Extremely light and compact 6x4.5 cm film format coupled rangefinder camera system with four interchangeable leaf shutter lenses: 45mm, 65mm, 100mm and 135mm. The 135mm Tele Lens soon was discontinued due to calibration problems of the rangefinder-system. Dedicated flash (RF20) and special polarizer kit.
