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. 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. Short telephoto prime is designed for full-frame Sony E-mount mirrorless cameras, however, can also be used with APS-C models where it provides a 202.5mm equivalent focal length. Bright f/2.8 maximum aperture suits working in difficult lighting conditions and also offers increased control over the depth of field for working with selective focus techniques. also contributes to notable sharpness, well-controlled flare, and high contrast. ZEISS T* anti-reflective coating has been applied to each lens surface to help minimize reflections and provide greater contrast and color fidelity. Optical image stabilization helps to minimize the appearance of camera shake for sharper handheld shooting. 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. The autofocus performance of the lens provides smooth, fast, and quiet operation. For manual focusing, a rubberized ring offers greater tactile control for precise placement of focus.
