Zeiss Milvus 18mm f/2.8 ZF.2 (Nikon)

The Nikon F-mount ZEISS Milvus 18mm f/2.8 ZF.2 utilizes a Distagon optical concept, with a pair of aspherical elements and four anomalous partial dispersion elements, to control distortion, spherical and chromatic aberrations, and color fringing in order to produce sharp, clear, and color-neutral imagery with a broad perspective. Additionally, Milvus-series lenses also feature an equally aesthetic and durable frosted, anodized metal lens-barrel surface along with a weather-sealed construction to protect against dust and moisture. Bright f/2.8 maximum aperture suits working in available-light conditions and is also well-suited for astrophotography use. Four anomalous partial dispersion elements are used to significantly reduce color fringing and chromatic aberrations for increased clarity and color fidelity. ZEISS T* anti-reflective coating has been applied to each lens surface to help minimize reflections and provide greater contrast and color fidelity. Manual focus design is benefitted by focusing and depth of field scales along with hard stops at both infinity and minimum focusing positions. Weather-resistant construction includes internal seals to guard against dust and moisture as well as a blue sealing ring at the lens mount to protect the lens-camera interface.
