• Short-telephoto, portrait-length prime is designed for full-frame Canon EF-mount DSLRs, however, can also be used with APS-C models where it provides a 136mm equivalent focal length.
• Bright f/1.8 maximum aperture benefits working in low-light conditions and also affords greater control over the depth of field for working with selective focus techniques.
• 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.
• A ring-type Ultrasonic Motor (USM) is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override. Additionally, the front of the lens does not rotate during focusing to better permit working with polarizing and graduated filter types.
• The rounded eight-blade diaphragm contributes to a pleasing out-of-focus quality that benefits the use of shallow depth of field and selective focus techniques.
