Mixing advanced optics with contemporary performance, the Batis 135mm f/2.8 from Zeiss is a mid-length telephoto prime designed for full-frame E-mount mirrorless cameras. Characterized as an apochromat, the Sonnar optical design helps to virtually eliminate chromatic aberrations and color fringing, and also benefits overall sharpness and clarity. Additionally, a T* anti-reflective coating has been applied that suppresses lens flare and ghosting when working in strong lighting conditions. Complementing the optical performance, the Batis 135mm f/1.8 also sports a unique OLED display on the top of the lens barrel to indicate focus distance and depth of field range for quickly recognizing your focusing parameters. In regard to autofocus, a linear motor delivers quick and quiet focusing performance and, additionally, optical image stabilization is also featured to minimize the appearance of camera shake for sharper handheld shooting. An ideal portrait-length lens, this telephoto prime has been designed specifically for full-frame Sony E-mount mirrorless cameras, however it can also be used on APS-C models where it will provide a 202.5mm equivalent focal length. Apochromatic Sonnar optical design significantly reduces color fringing and chromatic aberrations for increased clarity, sharpness, and color fidelity. Zeiss T* anti-reflective coatings have been applied to each lens surface to help minimize reflections in order to provide greater image clarity, contrast, and color fidelity.=
