Apo Grandagon 4.5/45 mm, used Copal 0, Image circle at 1:infinite=131mm Price include 19% German TAX/VAT Apo-Grandagon When large format cameras are used with roll film backs, they require shorter focal length lenses. With the focal lengths of 35, 45 and 55 mm of the Apo-Grandaon lenses, photography in close spaces or panoramic views in landscape photography becomes an effortless “dynamic enjoyment”. The Apo-Grandagon ultra-wide angle lenses give you the freedom to find new and appealing views in product photography. But new standards in freedom of movement are also offered by these outstanding lenses with a useful field angle of 120° in architectural and industrial photography. The Apo-Grandagon 55 mm f/4.5 even allows photographs of, for example, wide open spaces on 4x5 in. sheet film which is most popular in demanding landscape photography. New glass combinations (ED glasses) make possible apochromatic correction of ultra-wide angle lenses for the first time. This ensures there will be no color fringes even on high contrast building silhouettes against bright sky. With values of less than 0.5%, distortion can be neglected. The high maximum aperture makes adjustment easy. A large working aperture of 8-11 allows advantageous, shorter exposure times for outdoor motifs (with moving objects) or a lower flash power in the studio. For uniformly illuminated pictures without light fall-off according to the cos4 law, the use of the color-neutral Rodenstock center filters is recommended. With the Rodenstock Focus-Mount, these lenses can be fitted to panoramic or shift cameras without bellows. For checking the adaptation to different large format camera models, we can provide you with special tables and instructions on request.
