The Rodenstock 120mm f/5.6 Apo-Macro-Sironar Lens with Copal Shutter & Lensboard from Arca Swiss is optimized for close-up medium and large format analog photography. It comes with a Copal shutter and lensboard for stepless mechanical action. Also, the lens produces a 210 mm image circle for formats up to 4 x 5" in size.
