A truly wide-angle prime characterized by its advanced optical design and unique physical attributes, the Batis 18mm f/2.8 Lens from Zeiss is designed for full-frame Sony E-mount mirrorless cameras. The innovative design of this lens features an OLED display that highlights the focus distance and depth of field range for quickly recognizing your focusing parameters, and autofocus is handled by linear motors that maintain quick, quiet, and smooth performance. In regard to optics, the lens employs a Distagon concept with a floating elements design that maintains consistent sharpness and illumination throughout the focusing range, and a series of aspherical and special glass elements help to control both chromatic and spherical aberrations. A Zeiss T* anti-reflective coating has also been applied to individual elements in order to suppress flare and ghosting for improved contrast and color fidelity, and the lens also sports a dust- and moisture-sealed design to permit its use in trying environments. Well-suited to interior, architectural, and astrophotography applications, the Batis 18mm f/2.8 blends its extremely wide 99° angle of view with a high degree of functionality.
