ZEISS Loxia 21mm f/2.8 Lens | Sony E-Mount

The ZEISS Loxia 21mm f/2.8 is a sophisticated wide-angle prime lens that merges a broad field of view with a compact design, specifically crafted for full-frame Sony E-mount mirrorless cameras. Utilizing the Distagon optical design, this lens incorporates four anomalous partial dispersion elements alongside one aspherical element, significantly reducing chromatic and spherical aberrations, thereby enhancing color accuracy, sharpness, and overall clarity. To combat flare and ghosting, an advanced ZEISS T* anti-reflective coating has been applied, making it advantageous for use in challenging lighting situations.

Loxia-series lenses are notable for their manual focus functionality and a manual aperture ring that can be de-clicked for silent adjustments, rendering them particularly well-suited for filmmaking. Furthermore, these lenses feature a compact build and an all-metal lens barrel, which includes engraved scales for focusing and depth of field, allowing for precise control. The lens body is also designed to be dust- and moisture-resistant, 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 provides a 31.5mm equivalent focal length
• Bright f/2.8 maximum aperture suits working in available-light conditions and is also well-suited for astrophotography use.
• Distagon optical concept affords high sharpness, well-corrected image quality from edge-to-edge, and very low field curvature.
• Four anomalous partial dispersion elements are used to significantly reduce color fringing and chromatic aberrations for increased clarity and color fidelity.
• One aspherical element controls distortion and spherical aberrations in order to produce greater sharpness and more accurate rendering.
• ZEISS T* anti-reflective coating has been applied to each lens surface to help minimize reflections and provide greater contrast and color fidelity.
• Manual focus design is benefitted by focusing and depth of field scales along with a 90 focus ring rotational angle and hard stops at both infinity and minimum focusing positions.
• Manual aperture ring has clicked indicators throughout aperture range. Using the included De-Click Tool, this ring can be mechanically ‘de-clicked’ for smooth, silent rotation throughout the aperture range; making it ideal for video applications.
• Weather-resistant construction includes internal seals to guard against dust and moisture as well as a blue sealing ring at the lens mount to protect the lens-camera interface.
• The lens mount is fitted with an electronic interface that conveys all lens Exif data to the camera and can also be configured to automatically activate the camera’s focusing magnification function when turning the focus ring.
