Updating a tried-and-true optical design for use with full-frame Sony E-mount mirrorless cameras, the Batis 85mm f/1.8 from ZEISS is a portrait-length, short telephoto lens featuring a fast maximum aperture for greater focus control and enhanced low-light shooting. The Sonnar-type design, in conjunction with three anomalous partial dispersion elements, offers high contrast and accurate rendering by virtually eliminating color fringing and chromatic aberrations. A floating elements system is also used, for consistent performance throughout the focusing range, in order to achieve even sharpness and clarity. An enhanced ZEISS T* anti-reflective coating has also been applied to significantly reduce ghosting and lens flare for improved contrast and color fidelity when working in difficult lighting conditions.
