Product Description Pairing the tested Distagon concept with contemporary functionality, the ZEISS Batis 25mm f/2 is a wide-angle prime designed specifically for full-frame Sony E-mount mirrorless cameras. Its broad field of view makes it well-suited to landscape, reportage, and architecture photography applications and the bright f/2 maximum aperture is ideal for shooting in low-light conditions. The optical design 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 is also employed for consistent performance throughout the focusing range, and an enhanced ZEISS T* anti-reflective coating has been applied to reduce flare and ghosting for working in difficult lighting conditions.
