Today I received a 120 Mamiya macro lens that I purchased on ebay. The seller represented the lens as a "D" version, but it is not. It appears to be 2006 vintage and is in great condition, but I have been unable to test it as my PhaseOne camera has yet to arrive. Aside from the 16 bit chip, are there optical differences between this lens and the current "D" versions from Phase and Mamiya? Is this worth making a fuss about from a user point of view, putting ethical matters aside for now?
Many thanks!
