Zeiss has officially announced the upcoming launch of its new 55mm f/1.4 lens, the Zeiss Otus 1.4/55. Otus is the Latin name for a type of owl known for its excellent vision in darkness, so the product name hints at the remarkable low-light capabilities of the new lens. Indeed, Zeiss claims that the Otus 1.4/55 "creates the highest-possible image quality, even with an open aperture." Other unique features of the Otus 1.4/55 are its high image contrast all the way to the edges (even for low f-numbers) and the consistent high-resolution performance across the entire image field. The optical formula incorporates a floating elements design with 12 elements in 10 groups, including a double-sided aspheric lens element and six elements made of special glass with anomalous partial dispersion. The Zeiss Otus 1.4/55 will be available for Nikon (ZF.2) and Canon (ZE) mounts, starting at the end of October in all global markets. The recommended retail price will be €2,940 or US$3,999.

Three lens elements made from glass with anomalous partial dispersion minimise chromatic aberrations, and two further elements are manufactured from glass with particularly low dispersion. An additional lens element with an aspherical surface minimises monochromatic aberrations. Thanks to its extremely elaborate optical design and construction, the lens also offers excellent control of flare to ensure high-contrast images, even when shooting a backlit subject. The suggested retail price for the Leica Elmarit-S 45 mm f/2.8 ASPH. without an integrated leaf shutter is £4,650; the SRP for the central shutter (CS) versionof the lens is £5,500.
