Zeiss has introduced a new high-performance Otus 55mm f1.4 lens for discerning photographers. Modern D-SLR sensors put enormous demands on lenses. Otus is the Latin name for a type of owl known for its excellent vision in darkness. The Otus offers greater sharpness, high image contrast and no visible chromatic aberrations. The lens is made with the distagon optical design, which is usually found on wide-angle lenses. It is equipped with a floating elements design with 12 lens elements in 10 groups, including a double-sided aspheric lens and six lenses made of special glass with anomalous partial dispersion. It is especially suited for advertising, fashion and studio photography. The Otus 55mm f/1.4 is the first lens in a new family of professional lenses from Zeiss. Additional focal lengths will follow.
