Normal-length prime is designed for full-frame cameras, however can also be used with APS-C models.
Impressively bright f/1.4 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.
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.
Floating elements system helps to maintain consistent image quality throughout the entire focusing range, from 1.5' to infinity.
Manual focus design is benefitted by focusing and depth of field scales along with hard stops at both infinity and minimum focusing positions.
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.
All-metal lens barrel has a frosted, anodized surface along with a rubberized focusing ring for both durability and improved tactile control.
