The Rollei badged Voigtländer was on display at Photokina, but the salesman face was like "Do you really want to see it?" and my face was "No, used surprised to see it at all". I can not remember to actually have seen one in a shop.
Most of the ZM-lenses were dummies, as both the 15 and the 85 were just front lens and otherwise empty. The 15 will be the most expensive at around 2200 Euro. The 85 in the catalogue looks small, actually it has a diametre like the Noctilux and to me looked bigger than the 90/2.0
