Normal 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/1.4 maximum aperture
suits working in low-light conditions and also affords great control over depth
of field for isolating subjects and using selective focus techniques.
Gaussian optics design, which
includes two high refractive index elements, notably reduces distortion and
spherical aberrations for high sharpness and accurate rendering.
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 micro 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.
