Bought this Exakta mount lens from a Camera show. Very compact lens for an 85mm focal length. Has Pre-set aperture. Exakta mount can be removed. This lens was with both Exakta and Leica L39 mount. Since I don't have an Exakta adapter, I put a T-mount to Minolta Mount adapter over the Exakta mount (that's how small the lens and its mount is) and managed to use it to snap a few pictures. Unfortunately, as expected, I could not focus to infinity, only to about 2 meters.

Can't really say anything about the image quality yet. I only took a dozen pictures with it, and only a couple of them turned out viewable.
