Ultra-wide 20mm f/2.8 prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 32mm equivalent focal length.
Bright f/2.8 maximum aperture benefits working in low-light conditions and also permits working with shallow depth of field techniques.
Four aspherical elements limit distortion and spherical aberrations in order to realize greater sharpness and accurate rendering.
Two Super Ultra-Low Dispersion elements minimize color fringing and chromatic aberrations for high clarity and color accuracy.
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.
Floating rear focusing system maintains image quality throughout the focusing range.
