The Zeiss Milvus 50mm f/1.4 ZF.2 Lens is an ideal choice for portrait shots. It is designed for Nikon F-mount cameras and comes with 10 optical elements in 9 groups. Among these elements is one aspherical and four anomalous partial-dispersion glass elements that ensure reduced distortion and improved clarity. Each of the elements has a Zeiss T* anti-reflective coating that enhances image sharpness and contrast. The manual-focus system facilitates capture of clear shots from a close distance of 45 cm from the subject. The anodized metal barrel makes the lens easy to handle in cold weather. Moreover, the lens has a rubberized focus ring for better control while focusing. You may use a circular filter on the front 67mm thread of this lens.
