Today I finished the special mount for the Rodenstock super wide angle lens. I have to make a sunk mount for the lens to aware that the rear lens shutter of the Sinar system limitate the angle of view.
Rodenstock listed the lens with 105°.
So I have to test it with 18x24cm sheet film size. Here the lens has to cover 100° angle of view.
In the corners the sharpness ist not perfect but I find it realy remarkable that the corners are not dark, the lens shows only minimal vignetting.
The lens has a very good sharpness and has no focus shift like so many of the Dagor style lenses have.
I take the sample with f/45.
