Featuring an apochromatic design and utilizing the Distagon concept to reduce distortion, this lens uses a series of eight anomalous partial dispersion glass elements and two aspherical elements to virtually eliminate chromatic and spherical aberrations throughout the aperture range. A floating elements system is also used for consistent performance throughout the focusing range and a Zeiss T* anti-reflective coating has been applied to significantly reduce ghosting and lens flare for improved contrast and colour.

It is a manual focus lens, complemented by a 120° rotational focus throw, rubberized focus ring, and an all-metal lens barrel with high-visibility yellow scale markings.
