Canon EF 50mm F1.4 USM
- 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 one aspherical element and 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.
