The Eka came out around the time of the Leica in 1925. It used un-perforated 35 mm film and so took larger images than the Leica. A measuring wheel locks when the film has been sufficiently advanced, to unlock the wheel a small catch is moved, which also advances the frame counter. A metal block pulls out from the base of the camera providing a tripod socket for vertical or horizontal exposures.
