35/2 Summicron in Contax mount?

[R.MacDonald]

Looking around on the auction site I stumbled upon this:

I've heard of Zeiss lenses on a Leica, but never the other way around. I imagine it's a hacked lens, but it sure does look funny seeing a Summicron on a Contax.

Looking by how the conversion was made (fit into 50mm Contax inner mount), it will not focus properly except on infinity.

They sould have used a J-12 mount to acheive RF coupling. I've done some conversions to Contax RF and Nikon S-Mount using the inner helical. I converted a Kodak Anastigmat Special in shutter to Nikon mount. Set the camera on "T" and use the leaflet shutter in the lens.
