The Zeiss Batis Distagon T* 2/25mm is a full-frame (FE) wide-angle prime lens for the Sony E-mount, announced by Zeiss on April 22, 2015.
Though designed for Sony's full frame E-mount cameras, the lens can be used on Sony's APS-C E-mount camera bodies, with an equivalent full-frame field-of-view of 37.5mm.
The lens features a weather resistant aluminum barrel construction with a matte black finish and a rubber focus ring. Along with the Zeiss Batis Sonnar T* 85mm F1.8, the Batis Distagon 25mm was one of the first two lenses in which the traditional distance scale on the lens is replaced with an OLED display. The OLED display is integrated into the top of the lens barrel, and highlights the focus distance and depth of field range of the lens, which can be set to display at all times, never, or only when focusing manually.
