the Canon EF 100mm f/2 USM is a short-telephoto prime characterized by its slightly compressed perspective for achieving flattering results. Its bright f/2 maximum aperture also benefits using a shallow depth of field techniques as well as working in low-light conditions. Helping to achieve high color fidelity and contrast, a Super Spectra coating has been applied to individual elements and serves to minimize reflections, lens flare, and ghosting. Additionally, a ring-type USM is employed to deliver quick and quiet autofocus performance along with full-time manual focus control.
Short-telephoto, portrait-length prime is designed for full-frame Canon EF-mount DSLRs, however, it can also be used with APS-C models where it provides a 160mm equivalent focal length.
Bright f/2 maximum aperture benefits working in low-light conditions and also affords greater control over 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.
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.
