Four Low Dispersion Elements
Sonnar Optical Design
Short telephoto prime is designed for full-frame Canon EF-mount cameras, however can also be used with APS-C models where it provides a 216mm equivalent focal length.
Impressively bright f/2 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.
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.
Four 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.
Floating elements system helps to maintain consistent image quality throughout the entire focusing range, from 2.6' 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.
