The Batis 40mm f/2 CF from ZEISS presents a distinctive short-normal focal length combined with a close-focusing capability, specifically designed for Sony E-mount cameras. This lens is notable for its sophisticated optical configuration, which is rooted in the Distagon design. It incorporates a selection of aspherical and anomalous partial dispersion elements that significantly minimize color fringing, distortion, and various aberrations, resulting in imagery that is sharp, clear, and true to color. The inclusion of a floating elements system, along with the Close Focusing feature, ensures reliable performance when capturing subjects at both close and distant ranges. Furthermore, an advanced ZEISS T* anti-reflective coating has been applied to mitigate flare and ghosting, making it suitable for challenging lighting situations.

The Batis series is recognized for its 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 capabilities, making it ideal for both photography and videography. Additionally, the lens is constructed with a dust- and moisture-resistant design, enabling its use in demanding environments.

• Short normal-length 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 60mm 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.
• Suitable for close-up shooting, this CF (Close Focusing) lens has a minimum focusing distance of 9.4″, minimum working distance of 5.5″, and a maximum magnification of 1:3.3.
• Distagon optical concept affords high sharpness, well-corrected image quality from edge-to-edge, and very low field curvature.
• Two aspherical elements, three elements made from anomalous partial dispersion glass, and one aspherical element 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.
• 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.
