The Batis 85mm f/1.8 from ZEISS represents an updated version of a proven optical design, specifically tailored for full-frame Sony E-mount mirrorless cameras. This portrait-length, short telephoto lens boasts a rapid maximum aperture, facilitating enhanced focus control and improved performance in low-light conditions. Its Sonnar-type configuration, combined with three anomalous partial dispersion elements, ensures high contrast and precise image rendering by effectively minimizing color fringing and chromatic aberrations. Furthermore, a floating elements system is employed to maintain consistent performance across the entire focusing range, resulting in uniform sharpness and clarity. An advanced ZEISS T* anti-reflective coating has been applied to significantly diminish ghosting and lens flare, thereby enhancing contrast and color accuracy in challenging lighting situations.
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 utilizes linear motors to provide rapid, silent, and smooth focusing capabilities, making it suitable for both still photography and video recording. Additionally, this lens features optical image stabilization to reduce the effects of camera shake during use with slower shutter speeds, and its dust- and weather-sealed construction makes it well-suited for operation in demanding environments.
- Short-telephoto 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 127.5mm equivalent focal length
- Bright f/1.8 maximum aperture suits working in low-light conditions and also offers increased control over depth of field for working with selective focus techniques.
- Sonnar optical concept suits the combination of a large maximum aperture and long focal length, and also contributes to notable sharpness, well-controlled flare, and high contrast.
- Three anomalous partial dispersion elements are used to significantly reduce color fringing and chromatic aberrations for increased clarity and color fidelity.
- ZEISS T* anti-reflective coating has been applied to each lens surface to help minimize reflections and provide greater contrast and color fidelity.
- Optical image stabilization helps to minimize the appearance of camera shake for sharper handheld shooting.
- Floating elements system helps to maintain consistent image quality throughout the entire focusing range, from 2.6' 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.
