The Petri 7s was introduced by Petri in 1963 as a variant of the Petri 7 which was introduced in 1961. The main difference being an improved film advance lever and frame counter. It took 35mm film, had a coupled rangefinder, and an around-the-lens selenium cell light meter. Production ended in 1973.
Compared to its predecessor, the 7s is very advanced. It has ATL (around the lens) selenium metering with a match-needle visible both in the viewfinder as well as the top of the camera. From the 7s came the compact Petri Color 35, which was wildly popular when released in 1968
The 7s was available with either a 45mm f1.8 or f2.8 lens. The shutter had speeds up to 1/500, and the viewfinder used Petri's Green-o-Matic system.
