A portrait-length lens with no optical compromises, the Canon EF-mount Zeiss Otus 85mm f/1.4 Apo Planar T* ZE Lens resembles its namesake and seeks to deliver notable performance in any situation. Based on the Planar design, this apochromat incorporates one aspherical element and six elements made from anomalous partial dispersion glass in order to effectively suppress chromatic and spherical aberrations throughout the focus and aperture ranges. Additionally, a floating element design is also employed and a Zeiss T* anti-reflective coating has been applied to individual lens elements for consistent sharpness and image clarity. As a high-precision tool, the Otus 85mm f/1.4 also features a refined physical construction to endure use in trying conditions. The longer-than-normal focal length pairs well with the fast f/1.4 maximum aperture to enable precise control over focus position for shallow depth of field applications. Accentuating the range of control, this manual focus lens is complemented by haptic design elements, including a long rotational focus throw, rubberized focus ring, and an all-metal lens barrel with high-visibility yellow scale markings. This ZE-series lens is dedicated to Canon EF-mount cameras, and features an electronic interface to support camera-based adjustment over exposure settings.
