Any difference I put down to sample variations rather than design variation. Out of the four copies I tested, the copy I settled on was the Japanese market Version I (screw hood, f/2.8) in Nikon mount. It seems if there is a difference between Version I & Version II (both f/2.6-2.8 & f/2.8 models) it may be the optical coatings. The optical formula/design appears to be identical.
That said, I did end up getting the Angenieux model rehoused by KimCamera in Korea, and will be using that one with my UM46kPL.
