Recommended as a standard lens for photography where the demands for image quality and distortion correction are extremely high. The Planar CF 3.5/100 mm lens provides outstanding image quality and extreme freedom from distortion. At full aperture and when stopped down moderately, the image quality of the 100 mm Planar f/3.5 lens is even better than that of the 80 mm Planar lens. For this reason, the lens is recommended as a standard lens for photography where the demands for image quality and brilliance are high. The excellent distortion correction is also of great importance for architectural photography and for all applications which require an exact reproduction of the geometry of the object (e. g. for surveying).
