*Contax mount is quite different. In fact it's two mounts. The inner mount has a focussing helical, so the standard lenses don't have one. The outer mount is for other lenses which have their own focussing device. Its difficult to measure. I have taken the locking pin for reference.

Closest focus  is 77cm from the outermost edge of the lens, F 8. Focus on the program wheel of the camera.

This lens was a newer standard lens sold with Kiev cameras. It can be found for low prices, it's very decent. Wide open it's quite soft at edges. Stopped down a little bit, it's sharp already. The lens has no close focussing capablities. It is relatively small and lightweight, particularly for a F 1.8 lens. A nice lens which offers one usable stop more than a standard lens.

The Contax rf mount adapter is difficult to find and sometimes expensive, but Contax mount lenses are often much cheaper than their M39 versions.
