I have a 135mm Heliar lens from an old Voigtlander Avus 9x12 camera. I have mounted it on a board for Pacemaker Speed Graphic. What can I expect from such a lens? Will it outperform my 127mm Kodak Ektar? I have an Avus with a Skopar lens. The lens is fantastic, especially in mono. Are Skopars considered superior to the Heliars? Some people say the lenses produce different moods.
