The Kochmann Korelle 3×4 camera was a little folding camera for 3×4cm exposure format. Nowadays it reminds us of modern compact cameras despite of it's heavyweight cute metal body which is covered with leather or leatherette. As a viewfinder the camera has two frames which unfold into view-through position by pressing the camera's unfolding button. A version with a little optical viewfinder and an accessory shoe was available.
