*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. This one uses the outer mount.

Some pictures:

A7 and the lens.

Sample pictures: You may click on the sample image (except closest focus) for full resolution. The full resolution image opens in a new window, so you can keep it open for comparison. Focus is on the satellite dish to the right of the big solar panel near the center of the photo.

F 2.0.

F 8.

F 22.

Closest focus is 95cm (!)  from outermost edge of the lens, F 8. Focus on the program wheel of the camera.

This old lens was sold for Kiev cameras. The Kiev version can be found for moderate prices because the mount is rare, it's nevertheless a decent and luminous portrait lens. Wide open mine is fine, better than the Zenit version I have. Stopped down, it's just sharp. The lens has nearly no close focussing capablities, but it's again better than the Zenit version. A very nice lens which offers luminous portrait facitities.

The Contax rf mount adapter is difficult to find and sometimes expensive, but Contax mount lenses are often much cheaper than their M39 versions. This lens was cheap and I already had the adapter. Otherwise there is no real advantage in comparison to the M39 model. For this lens the M39 Zenit version is the cheapest and weighs less for the combination adapter/lens than the Contax or the difficicult to find M39 rangefinder version. The reason is that the heavy build quality of the Jupiter tube weighs much more than an adapter.
