Alpa Model 7 (1952-59) Similar to model 5 with diecast magesium alloy body, bayonet lens mount, self timer added, and has both a penta prism and a regular viewfinder in order to handle both auto aperture and earlier preset lenses. Built-in finder has multi-focal capability (35, 70, 135), first to offer this. . Made by Pignons AG, Ballaigues, Switzerland. The Pignon business was a family owned business founded in 1918 originally to produce watches and clocks. Fluctuations in that field brought about the decision to go into the photography market making a camera that offered both reflex viewing and a rangefinder. The first cameras appeared in 1939 and the Alpa cameras blossomed in the 1950's- 60's. The company closed in 1991. Jacques Bolsey designed the cameras and then moved to the United States to form Bolsey Corp of America in New York, producing cameras from the late 1940's into the 50's.
