EF-Mount Lens/Full-Frame Format.

Aperture Range: f/1.8 to f/22.

Super Spectra Coating. To minimize ghosting and flare for greater contrast and colour neutrality when working in strong lighting conditions.

STM Stepping AF Motor realizes smooth, near-silent autofocus that is complemented by advanced AF algorithms and a high-speed CPU for fast AF performance. Additionally, a full-time manual focus override is also available.

Normal-length prime is designed for full-frame Canon EF-mount DSLRs, however, can also be used with APS-C models where it provides an 80mm equivalent focal length.

Bright f/1.8 maximum aperture enables control over depth of field for selective focus applications and also benefits working in low-light situations.

The redeveloped physical design incorporates a metal lens mount for durability as well as a re-located focusing ring to maintain a compact form factor.

A rounded seven-blade diaphragm contributes to a pleasing out-of-focus quality that benefits from the use of shallow depth of field and selective focus techniques.
