Bronica 6×6 focal plane

The first Bronica cameras were a series a 6×6 focal plane shutter SLRs, similar in concept to the Hasselblad 1000F.

Evolution

The first model is the Bronica Z. The Bronica D is a similar camera.

The Bronica S introduced in 1961, has new incompatible finders and backs. There were many features no longer on the Bronica S that were available on the previous models including: 2 to 10 sec and 1/1250 shutter speed, self-timer, multiple exposure, focus lock. Improvements include a fool proof dark slide system. The camera will not function properly with a dark slide inserted nor can the back be removed without a dark slide. Dual cable releases are available, one on the shutter button, the other on the bottom base of the camera.

The Bronica C is the corresponding budget version of the S and S2, without the interchangeable back. It was released before the S2, but shares many of the same designs and functions. The Bronica C2 was released a year later, a few months before the S2. The improvements made to the S2 bodys were incorporated into a revised C2.

The Bronica S2, released in 1965, is the successor of the Bronica S. The new model included a number of minor changes, but the main improvement was the switch to a removable helical focusing mount. This helical mount could focus lenses with focal lengths from 40mm to 200mm; longer lenses had their own helicoids.

Because all of the camera functions are fully mechanical, no batteries are needed to operate it.

The S2 uses a vertical-travelling cloth focal plane shutter. Shutter speeds are available from 1 to 1/1000s and B. Flash sync uses X and FP on an automatic PC terminal at a 1/40s sync speed. The shutter must be cocked before each shot by cranking the film winding lever. The "Filminder" rollfilm back can use 120 or 220 film, selectable with a small dial on the film back. A peel-apart Polaroid back was also available for the S2. Film backs are removed from the camera by inserting a dark slide. As a safety feature, the shutter will not fire if the dark slide is not removed.

The standard lens for the S2 was a 75mm f/2.8 Nikkor P.

The Bronica S2A was released in 1969 and is the successor of the S2. Feature wise it was identical to the S2. The main difference is an improved film advance gear mechanism, reputed to result in fewer jams. Later models changed the camera strap lugs as well as no longer mentioning S2A in the serial number. In the used camera market; this caused some S2A to be sold at lower S2 prices.
