This lens is a new addition to Kodak's line of highest-grade precision lenses, which under the name of "Ektar" have won the acclaim of the really exacting and discriminating photographer. With its fast maximum aperture of f/3.5 this lens bring to photographic workers preferring larger negative sizes many of the picture-taking possibilities up to not restricted to miniature cameras. A carefully worked out formula, superior quality of the carefully chosen optical glass from which each one of the 5 elements is made, precision grinding, polishing and mounting, all contribute to make it a really outstanding lens. Aberrations, especially those in any way affecting excellent color reproduction, are virtually non-existent. Greater clarity and brilliance of black-and-white negatives and also color purity in case of full-color pictures are assured by coating the inner air-glass surfaces of the lens. A coupled range finder and an automatic depth of field indicator aid in exact focusing. An auxiliary infrared focusing mark is provided.
