Bronica or Zenza Bronica (ゼンザブロニカ?) was a Japanese brand of medium format roll-film cameras, including rangefinder and single-lens reflex models.

Bronica cameras first appeared in 1958, when the company’s founder, Zenzaburo Yoshino, introduced a camera of his own design, the Bronica Z rollfilm camera, at the Philadelphia Camera Show. The name “Zenza Bronica” is reputedly derived from Zenzaburo Brownie Camera.[1][2] The Bronica Z and successor Bronicas, using large-coverage, high-quality Nikkor lenses, became instant successes.

Bronica later introduced lenses of its own manufacture with its later camera designs. Zenza Bronica Ltd. was eventually acquired by the lens manufacturer Tamron. Zenzaburo Yoshino died in 1988.

Tamron discontinued the brand’s single-lens reflex models (SQ, ETR and GS) in October 2004. Bronica’s last model, the RF645 rangefinder camera, was discontinued in October 2005.[3]

Bronicas were workhorse cameras for wedding and portrait photographers for many years. Secondhand Bronica cameras are still widely used by professional and serious amateur photographers, in no small part due to superior image quality of 6×4.5, 6×6 and 6x7cm roll film over smaller film and digital sensor formats.

Bronica SLR cameras employed a modular design: The major components of the camera—lens, body, film back and viewfinder—were separate and interchangeable.

The Zenza Bronica ETR is a series of 4.5×6 SLRsmanufactured by The Zenza Bronica Industries Inc., Tokyo, Japan.

  1. Hi

    Don’t know if my comment worked. It looked strange. So I’m writing again. I’m looking for a work shop manual for Bronica SQ-A. Any chance you can fix that for me?

    Regards Hans Wahlgren
