Product description

• 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.
