Sinar Sinaron W MC f/4.5 90mm Lens (Grandagon-N) . Condition - 6E [7616].
Short Description
From Rodenstock literature:
With the Sinaron-W / Grandagon-N all the problems which occur in connection with large field angles have been ideally taken care of: wide-angle lens 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); and the sharpness sets standards for this class of lens.
102 degree viewing angle.
