Spanning a versatile wide-angle range, the EF 17-40mm f/4L USM Lens is a Canon L-series zoom featuring f/4 – f/22 aperture ranges.
One Super UD element is featured, along with three aspherical elements, which help to reduce both chromatic and spherical aberrations in order to realize high sharpness, clarity, and color accuracy.
A Super Spectra coating has also been applied to suppress flare and ghosting for improved contrast in difficult lighting conditions.
This wide-angle zoom also features a ring-type USM and internal focusing mechanism to afford quick, quiet, and accurate autofocus performance, as well as full-time manual focus override.
This lens is weather-sealed
