Mixing advanced optics with contemporary performance, the Batis 135mm f/2.8 from ZEISS is a mid-length telephoto prime designed for full-frame Sony E-mount mirrorless cameras. Characterized as an apochromat, the Sonnar optical design, along with the use of eight anomalous partial dispersion elements, helps to effectively eliminate chromatic aberrations and color fringing for improved clarity and rendering. A floating elements system is also used, for consistent performance throughout the focusing range, in order to achieve even sharpness and illumination. 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.

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, this lens incorporates optical image stabilization to minimize the appearance of camera shake when working with slower shutter speeds and a dust- and weather-sealed construction lends itself to shooting in trying environments.
