Wide-angle prime is designed for APS-C-format Sony E-mount mirrorless cameras and provides an 18mm equivalent focal length.
Bright f/2.8 maximum aperture suits working in available-light conditions and is also ideal for astrophotography use.
Distagon optical concept affords high sharpness, well-corrected image quality from edge-to-edge, and very low field curvature.
The optical design utilizes three anomalous partial dispersion elements to reduce color fringing and chromatic aberrations for increased clarity and color fidelity.
Two aspherical elements control 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.
Floating elements system helps to maintain consistent image quality throughout the entire focusing range, from 7.1" to infinity.
DC autofocus motor delivers quick and quiet focusing performance to suit both stills and video shooting applications.
