Petri Auto Semi First

The Auto Semi First represents Petri's entry into the 35mm market in 1940. As a relatively straightforward model of its era, it likely offered basic functionality in a compact package. Designed for general photography use, it probably featured a central shutter, coupled rangefinder focusing, and a basic set of shutter speeds and apertures, reflecting standard 35mm camera design for the late pre-war period. Its significance lies in being part of Petri's early product line during a formative period for 35mm photography, rather than in any groundbreaking design or technological innovation.
