Carl Zeiss Otus 55mm f1.4 APO-Distagon Camera Lens: ZF.2 Nikon

In contrast to its predecessors with similar focal lengths and speed, this is first time that the Distagon type has been selected for the optical construction of a standard lens. Only this optical design with its considerably longer construction makes it possible to already realise consistently excellent correction from corner to corner of the frame and extremely low image field curvature at a very large initial aperture. 

Key Features

- Distagon with 12 lens elements in 10 groups

- Lens with aspheric surface

- Lens made of special glass with anomalous partial dispersion

- "Floating Elements" design

Spectacularly detailed portraits full of contrast. High fidelity images and exceptional performance into the corners even at full aperture. The Otus 1.4/55 makes absolutely no compromises and brings together over a century of ZEISS optical and technical excellence. This standard lens is the exception to the rule: perfect optical correction eliminates nearly all possible flaws, from color fringes and distortion to chromatic aberrations. With the highest contrast performance over the entire image field, even at an aperture of f/1.4, this lens offers the spectacular medium format look when working with a modern SLR camera. Phenomenal detail and exceptional performance, regardless of whether it’s using available light or in the studio, the Otus 1.4/55 is the absolute best lens in the world today.
