The Zeiss Milvus 35mm f/1.4 ZE Lens for Canon EF Mount features an advanced optical design that virtually eliminates color fringing and other aberrations while providing greater image clarity and color accuracy. A new special coating greatly reduces ghosting and lens flare while the Distagon-type design ensures maximum quality and sharpness, especially when using a very wide aperture on a high-megapixel camera. Note that this is a manual focus only lens that sports a comfortable rubberized ring for precision control over your focus. manual focusing is further benefited by engraved focusing and depth of field scales, along with an IR position dot for those using modified cameras. There are hard stops at both infinity and minimum focusing positions. The minimum focusing distance is a relatively-close 11.81". This lens is made of anodized metal and is weather resistant with a sealing ring at the mount great for using with a weather-resistant camera. The Zeiss Milvus 35mm can be paired with both full frame and with crop frame sensor cameras. The focal length equivalent on crop frame sensors is 56mm. This wide/normal focal length prime lens is ideal for group portraits, environmental portraits, street photography, and event videography.
