Design and Features
High contrast and the best resolving power across the entire range of focal lengths, an outstanding flatness of field and low coma that can be eliminated completely by closing the aperture down by only one stop – these are some of the qualities that distinguish this zoom lens. Thanks to its range of focal lengths and its near-focusing distance of only 1.7 m (5’7"), it offers great flexibility for medium and longer tele distances. With the use of the Leica extenders and with a flick of the wrist, this lens, which can be compared with lenses with fixed focal lengths, becomes an optical system for universal applications. In effect, the extremely large spectrum of focal lengths provides the photographer with extensive possibilities in many diverse situations.
