This sale is for a Mamiya RB67 fit Vivitar 2x Converter lens in really excellent condition, and of course in perfect working order.
This lens is mechanically perfect and optically perfect, and with only normal very minor signs of use. Please note that there is no front cap included with this lens, although the rear cap is still there.
My asking price for this lens is just ?49.95 due to the missing front cap. A real bargain – and very difficult to find.
