The Alpa Reflex 1 (commonly known as simply the Alpa Reflex) is one of the most fascinating early 35mm single-lens reflex (SLR) cameras.
Although it never achieved the production numbers of the Kine Exakta or later German and Japanese SLRs, it established Switzerland as a maker of precision photographic equipment. It became the foundation of the prestigious, if somewhat quirky, Alpa series of cameras.
