Detailed Information Rodenstock Filters for Digital Photography
New color-neutral center filters for compensating the physically induced significant falloff in ilumination of super wide-angle lenses.
Conventional center filters for wide-angle lenses with image angles larger than 100° reduce the fall-off in illumination of 2 to 3 f-stops by reflection and absorption of their neutral density coating that gradually gets darker to the center. But this reflection produces stray light. The new Rodenstock center filters work only by absorption, hence they provide more brilliant and neutral pictures.
