The Zeiss Batis 25mm f/2 for Sony E-mount is a high-quality wide-angle lens designed specifically for full-frame E-mount cameras like the Sony Alpha a9, a7R III, a7 III, and a7S II. Key features include:

Great for architecture, landscape, and interior photography
Fast, nearly silent autofocus
Integrated OLED for focal length and depth of field
Advanced optical design
Full-Frame Wide Angle. Designed with the full-frame Sony E-mount cameras in mind, the Batis 25mm f/2 gives you a true wide-angle option for the system. It has a 82º angle of view with minimal distortion, making it ideal for architecture, landscape, and interior photography. The fast f/2 aperture gives you low-light shooting capability and shallow depth of field.

Autofocus. While the Loxia line gives you great manual-focus/aperture lenses, the Batis line provides you with autofocus capability. Its linear motor offers fast, nearly silent performance.

OLED Display. While many lenses use focus-distance and depth-of-field scales, the Batis lenses forego this for an OLED display. It functions exactly like the traditional methods, but provides the enhanced ability to see these parameters in low lighting.

Advanced Optics. The Distagon eight-group/ten-element optical formula includes four double-sided aspherical elements to cover corner-to-corner sharpness while controlling distortion. The floating element design helps to eliminate aberrations throughout the focusing range. Carl Zeiss T* anti-reflective coating eliminates lens flare and ghosting while providing the famous high micro-contrast Zeiss look.

High-Quality Build. Like other Zeiss offerings, the Batis line features great build quality. Cosmetically, they look quite similar to the Touits, with their metal construction and rubberized focus rings. However, the Batis lenses can boast dust- and weather-sealed construction for peace of mind in inclement shooting conditions.
