Chronology of cameras Bronica

M. Zenzaburo Yoshino, an industrialist from Japan¹, aimed to create the best Japanese camera post-war by openly drawing inspiration from the proven techniques of Hasselblad. The first Zenza Bronica model, the Z, was introduced in 1958. In 1961, the D and S models were released.

The models continued to evolve until the early 2000s. They were single-lens reflex cameras with interchangeable lenses and backs. The early models featured a focal plane shutter, later replaced by models with a leaf shutter. They were available in 6 x 4.5 cm or 6 x 6 cm formats, using 120 film.

The Bronica ETRS was the first improvement to the ETR, introduced from 1979 onward. The main enhancements included:
- Compatibility with the AE-II and AE-III viewfinders through a new connection.
- A new three-position shutter release (unlock, cable release only, and fully locked).
- A 2-tab system for ejecting the film back.

This model is equipped with a Zenzanon MC 50mm lens with a maximum aperture of 2.8 (minimum 22). The shutter is on the lens, but the speed is controlled on the camera body. The shutter delivers speeds ranging from 8 to 1/500, plus the T (time) setting.

The AE-II viewfinder is attached, along with the rapid grip (featuring an accessory shoe and a film advance lever) and an ETR 120 film back. The body is entirely made of metal but will later be replaced by plastic.
