The ZEISS Batis 25mm f/2 combines the established Distagon concept with modern functionality, making it a wide-angle prime lens specifically crafted for full-frame Sony E-mount mirrorless cameras. Its extensive field of view is particularly advantageous for landscape, reportage, and architectural photography, while the bright f/2 maximum aperture facilitates shooting in low-light situations. The optical configuration incorporates a series of aspherical and anomalous partial dispersion elements, significantly minimizing color fringing, distortion, and other optical aberrations to produce sharp, clear, and color-accurate images. A floating elements system is utilized to ensure consistent performance across the entire focusing range, and an advanced ZEISS T* anti-reflective coating has been applied to mitigate flare and ghosting, enhancing usability in challenging lighting conditions.
The Batis series lenses are notable for their pioneering integration of an OLED display on the lens barrel, which indicates the focus distance and depth of field range, allowing for quick assessment of focusing parameters. As an autofocus lens, it employs linear motors to provide rapid, silent, and smooth focusing performance, making it suitable for both still photography and video recording. Furthermore, the lens body features a dust- and moisture-sealed construction, enabling its operation in demanding environments.
- Wide-angle prime is designed for full-frame Sony E-mount mirrorless cameras, however can also be used with APS-C models where it will provide a 37.5mm equivalent focal length
- Bright f/2 maximum aperture suits working in low-light conditions and also offers increased control over depth of field for working with selective focus techniques.
- Distagon optical concept affords high sharpness, well-corrected image quality from edge-to-edge, and very low field curvature.
- Two aspherical elements, two elements made from anomalous partial dispersion glass, and a pair of aspherical elements also made from low dispersion glass are featured, and all contribute to significantly reducing chromatic and spherical aberrations, color fringing, and distortion for improved clarity, sharpness, and resolution.
- ZEISS T* anti-reflective coating has been applied to each lens surface to help minimize reflections and provide greater contrast and color fidelity.
- Floating elements system helps to maintain consistent image quality throughout the entire focusing range, from 7.9" to infinity.
- Integrated OLED display on the top of the lens shows the working focus distance as well as the depth of field range for quickly recognizing the parameters of focus in use, even when working in low-light conditions.
- Linear motors benefit the autofocus performance of the lens and provide smooth, fast, and quiet operation. For manual focusing, a rubberized ring offers greater tactile control for precise placement of focus.
- Dust and weather-sealed construction benefits using the lens in inclement shooting conditions.
