Chronology of cameras Alpa 

The Swiss company Pignons SA was founded in 1918 and specialized in producing mechanical parts used in watchmaking. Like many companies, diversification became necessary to offset market fluctuations and shortages. Pignons SA decided to venture into the field of photography.

The first camera prototypes were manufactured in 1939 under the brand name BOLSEY, among others.

The history of Alpa Reflex cameras spans over four decades, during which the models underwent significant evolution. Production is generally divided into four generations.

The first generation covers the period from 1942 to 1952. The models are named Standard, Reflex, or Prisma Reflex, and they were made of sheet metal. The Reflex and Prisma Reflex models had both a reflex viewfinder and a rangefinder viewfinder, with the reflex viewfinder mainly used for framing as it was not very precise. Its mirror had to be manually operated. The reflex viewfinder (chest viewfinder) was protected by a metal cover that also served as a sunshade when opened. The name Alpa-Reflex was engraved on this cover. The presence of three windows on the front easily identifies these models. The rangefinder viewfinder was effective for focal lengths up to 135mm. In the Prisma Reflex models, the reflex viewfinder was replaced by a black rectifying prism, and the viewfinder was at eye level. The models referred to as "Standard" did not have the reflex viewfinder.

In 1947, Pignons S.A. applied for a patent for a camera that had both a reflex viewfinder and a rangefinder (Patent No. 260,595). The rangefinder was positioned vertically, and the patent explained that this was the right solution because the upper part was occupied by the reflex system components. This principle would be found in the Model 7.

Cameras of the second generation (1952-1968) were now made from cast metal. They had discontinued the rangefinder viewfinder (except for the Model 7). In addition to the reflex viewfinder, they featured a direct viewfinder. The reflex viewfinder's mirror movement was automatic. The model and serial number were engraved on a small plate at the base of the prism. The early models were called Alpa Alnéa before becoming Alpa Reflex.

The appearance of third-generation cameras (from 1968 onwards) was significantly different, with a more modern silhouette. The prism cover had a flatter, wider shape and incorporated an exposure metering system behind the lens. They had a film winding lever that operated backward, which was different from the usual forward operation found in most cameras.

The fourth generation was the last one entirely manufactured by Pignons in Switzerland. The overall shape resembled other SLR reflex cameras from the 1970s and 1980s. The prism was laterally symmetrical. However, the film winding lever remained reversed from the common practice. The flash shoe was not located on the prism but on one of the two side plates.

Classifying Alpa models is complex, as is dating them. Reference authors sometimes disagree on the details.
