Delivering an impressively wide field of view, the Sony E-mount Batis 18mm f/2.8 from ZEISS is an ultra-wide prime, well-suited to interior, architectural, landscape, and astrophotography applications. Within the Distagon optical 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 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.
