Versatile Short Normal-Length Prime. Designed with the full-frame Sony E-mount cameras in mind, the Batis 40mm f/2 gives you a lens that’s superlative for up-close shooting. It boasts a 9.4-inch minimum focusing distance, a 5.5-inch minimum working distance, and a 1:3.3 maximum magnification. The fast f/2 aperture makes it great for low-light shooting and gives you extensive depth-of-field control. Using an APS-C camera? You’ll get a focal length equivalent to 60mm.
Linear Motor 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, smooth, and 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/nine-element optical formula includes two aspherical elements, three anomalous partial-dispersion glass elements, and one special aspherical glass element. The floating-elements design helps to eliminate aberrations throughout the focusing range, while the 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.
