The ZEISS Otus 55mm f/1.4 ZE Lens is a pinnacle of design for Canon EF-mount, offering unparalleled clarity, color precision, and performance even in low light conditions. The f/1.4 aperture enables depth of field control and subject distinction through selective focus. Employing a Distagon optical structure, the lens boasts superb corner-to-corner sharpness and minimal field curvature. Its optical engineering includes low dispersion and aspherical elements to curtail chromatic aberrations, color fringing, and distortion. A floating elements system enhances sharpness across all focus distances, complemented by a ZEISS T* anti-reflective coating to bolster contrast and color fidelity in harsh lighting. Manual focusing is precise and tactile with a rubberized ring, and the lens's robust anodized metal construction is accented with engraved scales and the Otus series' iconic high-visibility yellow details.
