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. 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. Wide-angle prime is designed for full-frame Sony E-mount mirrorless cameras, however, can also be used with APS-C models where it will provide a 37.5mm equivalent focal length. Distagon optical concept affords high sharpness, well-corrected image quality from edge to edge, and very low field curvature. Two aspherical elements, two elements made from anomalous partial dispersion glass, and a pair of aspherical elements also made from low dispersion glass are featured. The floating elements system helps to maintain consistent image quality throughout the entire focusing range, from 7.9" to infinity. Linear motors benefit the autofocus performance of the lens and provide smooth, fast, and quiet operation. For manual focusing, a rubberized ring offers greater tactile control for precise placement of focus. Dust and weather-sealed construction benefit from using the lens in inclement shooting conditions.
