Designed for landscape, press photography, machines, models and interior photographers, the Distagon 40mm f/4 lens concerts exceptional technical features which stands out from the rest in its class. The Distagon 40mm f/4 speed, angular field, and long back focal distance maintains a relatively minimal amount of distortion. This lens angle of view of 88° covers almost the same object field of the Biogon for the Hasselblad Superwide Camera.
