Zeiss Otus 1.4/28 EF-Mount

Bright-eyed and wide-angled, the Canon EF-mount ZEISS Otus 28mm f/1.4 ZE is an optically-refined prime poised to deliver a high degree of resolution and clarity in nearly any shooting condition. Featuring an apochromatic design, and utilizing the Distagon concept to reduce distortion, this lens uses a series of eight anomalous partial dispersion glass elements and two aspherical elements to virtually eliminate chromatic and spherical aberrations throughout the aperture range. A floating elements system is also used for consistent performance throughout the focusing range and a ZEISS T* anti-reflective coating suppresses lens flare and ghosting for increased contrast and color fidelity. Equaling the optical prowess of a Strigidae-inspired lens, the Otus 28mm f/1.4 is also characterized by a robust physical design for intuitive, exacting handling.

The wide-angle focal length pairs with the bright f/1.4 maximum aperture to suit working in broad variety of lighting conditions and is well-suited to a range of applications, including landscape, architecture, and interior photography. Accentuating the range of control, this manual focus lens is complemented by haptic design elements, including a rubberized focus ring and an all-metal lens barrel with high-visibility yellow scale markings.

Wide-angle prime is designed for full-frame Canon EF-mount cameras, however can also be used with APS-C models where it provides a 44.8mm equivalent focal length.
Impressively bright f/1.4 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.
Distagon optical concept affords high sharpness, well-corrected image quality from edge-to-edge, and very low field curvature.
Apochromatic optical design utilizes eight anomalous partial dispersion elements to significantly reduce color fringing and chromatic aberrations for increased clarity and color fidelity.
Two aspherical elements control distortion and spherical aberrations in order to produce greater sharpness and more accurate rendering.
ZEISS T* anti-reflective coating has been applied to each lens surface to help minimize reflections and provide greater contrast and color fidelity.
Floating elements system helps to maintain consistent image quality throughout the entire focusing range, from 11.8" to infinity.
Manual focus design is benefitted by focusing and depth of field scales, which are filled with a high-visibility yellow paint, along with hard stops at both infinity and minimum focusing positions.
All-metal lens barrel has a frosted, anodized surface along with a rubberized focusing ring for both durability and improved tactile control.
