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. Batis-series lenses are distinguished by their innovative use of an OLED display on the lens barrel, which highlights the focus distance and depth of field range for quickly recognizing your focusing parameters. As an autofocus lens, linear motors are used to deliver quick, quiet, and smooth focusing performance to suit both stills and video applications. Additionally, the lens body also sports a dust- and moisture-sealed design to permit its use in trying environments.
