Milvus 21mm f/2.8 ZF.2 for Nikon
Wide-angle prime lens
The Zeiss Milvus 21mm f/2.8 ZF.2 is a prime lens designed for FX format Nikon F mount DSLRs, and can also be used with DX models where it will provide a 31.5mm equivalent focal length. The bright f/2.8 maximum aperture benefits working in varying lighting conditions and also offers increased control over depth of field.
It uses the Distagon optical design to produce sharp imagery, even when working at the maximum aperture, and a floating elements system works to control chromatic aberrations and distortions. A Zeiss T* anti-reflective coating has also been applied to significantly reduce ghosting and lens flare for improved contrast and colour.
It is a manual focus lens, and features a rubberized focus ring for precise focus control. Use the laser-engraved focusing and depth of field scales, along with an IR position dot and hard stops at both infinity and minimum focusing positions for easy focusing. It also features a manual aperture ring with clicked indicators throughout the aperture range that can be manually de-clicked for smooth, silent rotation, ideal for video applications. All Milvus-series lenses feature a durable frosted, anodized metal lens barrel surface along with a weather-sealed construction with internal seals to protect against dust and moisture.
The new ZF.2 lenses are an enhanced version of ZF lenses. They feature an electronic interface (CPU) that enables support of all important camera operating modes such as shutter priority, aperture priority and programmed auto exposure or manual exposure settings. Photographers no longer have to set the parameters in the camera menu as the lens now transmits standard data such as focal length, speed and the aperture setting to the camera.
