Rodenstock 300mm f/5.6 APO-Sironar-N Lens with Copal #3 Shutter
The APO-Sironar-N, with 6 elements in 4 groups, is an all-around lens. Good for product shots, industrial subjects, landscape and city photography, it provides a longer focus lens with smaller formats. The image circle diameter exceeds the diagonal of the recommended format by around 45 percent, allowing abundant shift and swing possibilities.
