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.
Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions.
An 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, full-time manual focus override is also available.
Redeveloped physical design incorporates a metal lens mount for durability as well as a re-located focusing ring to maintain a compact form factor.
Rounded seven-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
