The Sony E-mount Batis 18mm f/2.8 from ZEISS is an ultra-wide prime, well-suited to the 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. 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. however, can also be used with APS-C models where it will provide a 27mm equivalent focal length. Bright f/2.8 maximum aperture suits working in available-light conditions and is also ideal for astrophotography use. Distagon optical concept affords high sharpness, well-corrected image quality from edge to edge, and very low field curvature. Two aspherical elements, five elements made from anomalous partial dispersion glass, and a pair of aspherical elements also made from low dispersion glass are featured. ZEISS T* anti-reflective coating has been applied to each lens surface to help minimize reflections and provide greater contrast and color fidelity. The floating elements system helps to maintain consistent image quality throughout the entire focusing range, from 9.8" to infinity. The integrated OLED display on the top of the lens shows the working focus distance as well as the depth of field range for quickly recognizing the parameters of focus in use, even when working in low-light conditions. For manual focusing, a rubberized ring offers greater tactile control for precise placement of focus.
