An expansive wide-angle for canon EF mount DSLRs, the Milvus 21mm f/2.8 ZE
Lens from zeiss utilises a Distagon design to control distortion and produce
sharp, clean imagery with a dynamic perspective. A floating elements system is
also employed for consistent performance throughout the aperture range and four
anomalous partial dispersion elements are featured to control chromatic
aberrations for increased clarity and sharpness. For minimising flare and
ghosting, an enhanced zeiss T* anti-reflective coating has been applied to
benefit working in difficult lighting conditions.
