Rodenstock 210mm f/5.6 APO-Sironar-N Lens with Copal #1 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.
