Korrelle K. A compact half-frame camera made by Kochmann in Dresden, Germany, known for the Reflex-Korrelle series. Produced around 1932.
It uses 35mm film in the 18×24 mm half-frame format and is equipped with a Compur-Rapid shutter with a top speed of 1/500. The lens is a non-coated Leitz Elmar 3.5 cm f3.5. Scale-focus type. Distance scale in meters, with a minimum focusing distance of 50 cm. The tripod socket on the base is the large thread type, but a small-thread adapter is attached.

The reddish-brown body is made of Bakelite. The combination of black paint and nickel plating creates a wonderful atmosphere. Although the construction might sound somewhat humble, the actual build is surprisingly refined, with an impressive sense of precision and density. The back opens by loosening a screw and pushing upward, a unique mechanism that adds to the charm. It is a camera you can truly enjoy handling and admiring.

The Korrelle K came with several lens variations, including Tessar, Trioplan, Xenar, and Tele-Xenar. Focal lengths ranged from 3.5 cm, 5 cm, 7 cm, 7.5 cm, to 10 cm.
Among them, the Elmar 35 mm f3.5 version is particularly rare and has long been prized by collectors.

Some brassing and paint wear can be seen in the areas where the hands typically make contact, but the body is overall in clean condition. There are no cracks in the Bakelite body.
It underwent an overhaul in November 2025, and all functions operate properly. When using the T setting, set the shutter speed to T and then use the lever below the shutter to release it.
Standard cassettes and universal magazines can be used, though a magazine is not included.
