Hello Rainer,
How does the lens preform when you are shooting a subject at an angle and have to deal with stretching of items on the edge? Is it better in this regard then other super-wide lenses? Also, does anyone know when Rodenstock plans on releasing the center filters for the HR23 and HR28?

well i dont know. in general this is an optical ley, caused by the distance of the objects and the viewing angle of non-fisheye lense, which dont show this type of distortion. there is no need for center filters and also no plans for centerfilter ( as far i know ) in the hr lenses because the light fall of is little.
