The Eka is an early 35 mm camera, made in about 1924 by E. Krauss in Paris. It makes 30×44 mm exposures on unperforated 35mm film, and holds enough film for 100 exposures.[1]

The camera has a 5 cm f/3.5 Tessar (marked for both Krauss and Zeiss; made by or for Krauss under licence), and a dial-set Compur shutter with speeds 1 - 1/300 second, plus 'B'.

It has helical unit focusing down to one metre;[2] the knurled focusing ring is accessed at the bottom of the camera, and the distance markings appear in a small notch in the front of the top plate.

The film advance key and frame counter window are on the bottom.[1] The winding key locks when the film has advanced a full frame. There is a sliding catch to unlock it to advance the film the next time; operating this catch causes the frame counter to advance.[2] There is also a covered tripod bush in the bottom.

There is a folding frame finder on the top.
