The Grandagon-N with its field angle of up to 105° can really display its strengths in wide photos in dose conditions, for example in architecture or industrial photography or in panorama views.
With the Grandagon-N all the Problems which occur in connection with large field arigles have been ideally taken care of: The distortion has been reduced to a small residual value; the light fall-off at the edge has been greatly reduced thanks to an optical trick ("pupil distortion" = the pupil diameter increases when viewing at an angle); the sharpness sets Standards for this class of lens.
The Grandagon-N is available in two versions: With the maximum aperture 4.5 in focal lengths 65 to 90 mm it has 8 elements and with the maximum aperture 6.8 in focal length 75 to 155 mm it has 6 elements.
The eight element lenses offer not only a high maximum aperture, but also a field angle of 109°, an even more uniform illumination and distortion values of less than 1%.
