Paweł Te Thanks a lot @Satoshi :) exactly that one without macro rings. in m4/3 there's crop factor x2, so it becomes a ~portrait lens. I bought it damaged for less than a 10$, I fixed it by myself, and now I'm quite happy with the results. Maybe it isn't the sharperst lens, but I like the way it renders the colors:)
Satoshi T Oh Mir 1b 37mm f/2.8 without macro ext. ring? Old wide angle lens revived brilliantly as a portrait lens of the present age! Great morning portrait!
