The User's Review: Phoenix, Promaster and Vivitar 100mm F3.5 Macro Lenses

The coating on the Vivitar front glass is more blue,
the other two has a similar coler, more pink.

With the screw-on adapter, 1:1 ratio can be achieved. Without the adapter, the lens can be uses as a 100mm prime. 

Besides the brand names on the front plates, another difference I notice is the coating colors on the front and rear glasses. However, I am not sure if the color variation is among the brand names or individual copies,
