The Rollei 35S is a remarkable feat of engineering — a fully mechanical 35mm camera that folds down to fit in a shirt pocket, yet features a high quality Sonnar 40mm f/2.8 lens. Made in Singapore from 1974, it is one of the smallest full frame 35mm cameras ever produced. Fully manual with zone focusing, it rewards a thoughtful approach to photography. The Sonnar lens produces beautiful, sharp images with pleasing rendering.
I replaced the battery with an adapter that supposedly changes the voltage - this worked well in the early days but now I am not so sure and use it with a shoe mounted light meter or my Gossen 6
