BARELY USED. PERFECT CONDITION the Batis 40mm f/2 CF from ZEISS is a Sony E-mount prime further characterized by its advanced optical layout. Based on the Distagon design, this lens uses a series of aspherical and anomalous partial dispersion elements to greatly reduce color fringing, distortion, and other aberrations to realize sharp, clear, and color-accurate imagery. A floating elements system, coupled with the Close Focusing designation, is also employed for consistent performance when working with both near and far subjects. Additionally, an enhanced ZEISS T* anti-reflective coating has been applied to reduce flare and ghosting for working in difficult lighting conditions.
