Tamron Adaptall 2 Ricoh RI Mount Adapter

Description

This is a well-used but not abused Tamron Adaptall 2 lens mount adapter to fit Tamron Adaptall 2 (and as I understand it, Adaptall lenses.  There are earlier Tamron interchangeable mount lenses that this does not fit.  It is made to mount Tamron lenses to Ricoh cameras.  It has electrical contacts that allow it to work on cameras that require them; I cannot tell you that these contacts work properly, as I have no Ricoh cameras.  It will also mount on Pentax K mount cameras, but NOT on ones that use auto exposure or would normally use K-A lenses, as the circuitry is not the same.  I tested it by mounting on 2-3 Tamron lenses that I have, and it mounted and functioned properly.  I have the price low, because I am selling it
