EF 50mm f/1.4 USM Lens
Offering a natural perspective along with a fast maximum aperture, the EF
50mm f/1.4 USM from Canon is a versatile normal-length prime characterized by
its bright f/1.4 aperture to suit working in low-light conditions and for
producing shallow depth of field imagery. This lens also features a Gaussian
optics design, along with two high refractive index elements and one aspherical
element, to control spherical aberrations and distortion for high sharpness and
clarity. A Super Spectra coating has also been applied to suppress flare and
ghosting for improved contrast and color accuracy when working in difficult
lighting conditions. Complementing the optical design is a micro USM, which
enables quick and quiet autofocus performance along with full-time manual focus
control.

Spanning a versatile wide-angle range, the EF 17-40mm f/4L USM Lens is a
Canon L-series zoom featuring a constant f/4 maximum aperture along with a
sophisticated optical design and durable construction. 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.
Complementing the imaging capabilities, 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.
Additionally, this lens is weather-sealed for use in trying environmental
