The Meyer version is the classic "zebra".

In available light with a Canon EOS 40D and a vintage Meyer-Optik Gorlitz Orestegor 200mm f/4 lens. 1/350th; 640 ISO. I bought this lens for £28 but the price also included a set of three M42 extension tubes, a Zenit-E camera, and an early example of the Helios-44 58mm f/2 lens. This remarkable lens was manufactured by Meyer Optik, Gorlitz, between 1963 and 1970 and has 15 aperture blades. It is a preset manual M42 lens, with continuous aperture - the aperture ring has no detents in it, and so it is stepless with a seemingly infinite number of aperture positions.
