The ZEISS Milvus 2.8/21 super wide-angle lens of the type ZEISS Distagon is the best in its class. Thanks to its maximum aperture of f/2.8, the reflection-free and practically distortion-free super wide-angle lens is perfect for spectacular image compositions of great diversity, dramatic contrast and vivid colors. The further optimization of the lens coating reduces ghosting and flare effects in critical light situations.
