ZEISS 25mm Batis f/2.0 Prime - E Mount

The ZEISS 25mm Batis f/2.0 Prime - E Mount is a wide-angle lens weighing 0.74 lb. It features fast and silent focus for Sony mirrorless, full-frame system cameras. The minimalist exterior design of the Batis line includes an easy-to-read OLED display with depth of field and the distance between camera and the focus plane.

The very close focusing distance of the 25mm wide-angle lens supports the creative implementation of exceptional perspectives. An extremely uniform image quality is ensured right into the corners of the image. The lens is the perfect companion for shooting landscapes, architecture, street scenes and photojournalism.

ZEISS Batis autofocus lenses were specially developed for mirrorless full-frame system cameras from Sony. Such SLR cameras had a mirror box, requiring a long back focal distance for short focal lengths (the distance between the back lens element and the film plane must be considerably longer than the focal length). The Distagon lenses (retrofocus design) are also ideal for mirrorless system cameras thanks to their optimized ray path (enabling excellent image performance with large image angles for digital camera systems without mirrors).

ZEISS Batis lenses are fully compatible with all Sony E Mount cameras.
