Bronica Z / D
The first model early on is often just called Bronica upon introduction. It was also called Bronica Z because of the big Z on the hood. It was produced in 1958.
The Bronica D or Bronica Deluxe is a very similar camera to the Z. The name was introduced in approx 1960.
Bronica S
The Bronica S introduced in 1961, has new incompatible finders and backs. It was originally designed as a simplified model of the deluxe. It's major improvement was a redesign of the gearing film advance system that has caused problems with the previous model. There were many features no longer on the Bronica S that were available on the previous models.
Bronica C
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 model C was quickly replaced with a nearly identical revision known as Bronica C2. It was released a year later, a few months before the S2. The C2 revision is often just called Bronica C as many markets did not have the original C. The improvements made to the body were incorporated into a revised C model along with 1/1000 shutter speed and 220 film compatibility.
Bronica S2
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.
The Bronica S2A was released in 1969 and is the successor of the S2. Feature wise it was identical to the S2.
Bronica EC
The Bronica EC was released in 1972. It has an electronically controlled shutter, and the Bronica EC-TL adds a TTL exposure meter. A newer revision called EC-TL II was also produced that changed the slow shutter speeds, because of that different finder screens are required.
