Bronica Rangefinder 645 Medium Format Camera

Bronica also known as Zenza Bronica existed as a medium format professional roll-film camera line, made in Japan which included rangefinder cameras and SLR cameras. Bronica cameras first burst upon the scene 1958, when, Zenzaburo Yoshino, the company's founder announced his own created camera , the roll film Bronica Z camera, at the camera show in Philadelphia. The Bronica Z, plus successive Bronicas, utilized large-exposure, high-quality Nikon lenses, were an instant sensation.

Later on, Bronica manufactured it's own with its successive camera models Zenza Bronica Ltd. later on was acquired by Tameron,  the lens manufacturer. Zenzaburo Yoshino passed away in 1988. in October 2004, Tamron stopped making the Bronica single-lens reflex brands (SQ, ETR and the GS), and production was halted on the last Bronica RF645 rangefinder brand in October of 2005. The Bronica cameras were mainstay for both wedding photographers and portrait studios alike for several years. Used Bronicas still see widespread use by professional photographers and serious amateurs, this is partly due to the superior quality of images of the 6x4.5, 6x6 and 6x6 and 6x7cm film when compared with smaller 35mm film and digital image sensor formats. The Bronica SLR cameras featured a modular design whereby all the major camera components. including the lens, camera body, viewfinder and film back were all separate but interchangeable units. updated article Apr 2, 2011

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 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.

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 and ETRC: Introduced November 1977 (ETR-C) and October 1978 (ETRC), production discontinued October 1980 (ETRC) and December 1980 (ETR-C). Identical to the ETR model except film magazine cannot be removed from film-back. ETRS: Introduced October 1978. Improved version of the ETR with an extra contact to support auto-exposure mode with the metered prism finder AE-II and later AE-III.

ETRS: A modification introduced July 1982, ETRS production discontinued September 1989. Unnamed change to original ETRS model. Lens release sliding lever latch located to left side of camera side panel, film-backs released using two independent tabs. This version is reputedly referred to as the "plastic" body ETRS and film-back, for the change in the side panels of the body and film-backs to polycarbonate.

Bronica SQ series

SQ-A: Introduced January 1982, production discontinued December 1991. 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.

SQ-Am: Introduced August 1982, production discontinued March 1991. Motorized film-advance only version of SQ-A body. Uses six additional AA batteries.

Bronica SQ-Ai 6X6 Camera Bronica SQ-Ai: Introduced December 1990, production discontinued December 2003
SQ-Ai: Introduced December 1990, production discontinued December 2003. Added the following functionality to the SQ-A. Ability to add the motor drive SQ-i and off the film (TTL-OTF) metering with select flash guns. These changes required the addition of a circuit board which also required the battery compartment to be "flattened." The single 6v cell was replaced with four 1.5 volt "button" cells. A bulb 'B' setting was added to the shutter speed selector. The film-back was also modified again with the introduction of the SQ-Ai, relocating the ISO dial to the rear of the film-back (rather than on top) to allow the speed setting to be seen better with a prism attached. Exposure compensation control was also added to the new SQ-Ai film-back, with the ISO range extended to 6400.

SQ-B (Basic): Introduced April 1996, production discontinued December 2003. The SQ-B was a manually operating SLR evolved from the SQ-Ai, built to primarily satisfy the needs of professional "studio" photographers who work with hand-held light meters, studio or portable flash equipment and various other accessories. Thus, motorized film-advance and through-the-lens metering (TTL) functionality were not present, as well as B (bulb exposure) and T (time exposure), as found on other SQ-series models. T (time exposure), however, was available when utilizing the appropriate SQ-series Zenzanon-S/PS lenses which incorporated the time (T) exposure lever function; by default the Zenzanon-PS/B 80mm f/2.8 lens which accompanied the SQ-B model did not include this feature. All SQ-series accessories and lenses were interchangeable with the SQ-B with few exceptions.
