I have a beautiful (looks new) Helios 103 in Kiev/Contax mount that I would like to trade for a Helios 103 in Leica Thread Mount - assuming they make such a lens.

Spyderman said:Max probably meant they will mount on Nikon, but because of the famous incompatibility issue (CLICK) the 50 and longer lenses for Contax / Kiev will not focus correctly on Nikons.
