Reportedly made in only ~300 copies, this is the crown jewel of the Super Takumars. Various reports say that it shares a design with the Contax Zeiss 15/3.5 or the Leica R 15/3.5. This copy is largely clean with no notable issues other than minor dust as pictured and notable on video, as well as minor use marks on the barrel. It has been converted to EF but can easily be converted back. What you see is what you get!
