Employing a no-holds-barred design, the Nikon F-mount ZEISS Otus 55mm f/1.4 ZF.2 is an optically refined normal-length prime characterized by its bright maximum aperture and advanced optics for high sharpness and color accuracy. The fast f/1.4 design excels in difficult lighting conditions and is also suitable for adjusting depth of field to isolate subject matter using selective focus. A Distagon optical concept is used to promote edge-to-edge sharpness and low field curvature, and, through the use of low dispersion and aspherical elements, this lens also achieves a well-corrected image quality void of aberrations, color fringing, and distortion. A floating elements system is also used, for consistent performance throughout the focusing and aperture ranges, in order to achieve even sharpness and clarity. An enhanced ZEISS T* anti-reflective coating has also been applied to significantly reduce ghosting and lens flare for improved contrast and color fidelity when working in strong lighting conditions.
