The EF 24mm f/1.4L II USM has a large maximum aperture of f/1.4, offering the
chance to capture superb low-light photographs, as well as a circular aperture
and narrow depth of field to give pleasing background blur. A focal length of
24mm is ideal for wide-angle photography: making the lens well-suited to the
needs of photojournalists, landscape photographers and those who enjoy taking
images from a wider perspective.
Image quality has been greatly improved with the EF 24mm f/1.4L II USM thanks to
the addition of two high-precision aspheric lenses to correct aberration
including curvature of field and distortion. Chromatic aberration common in
wide-angle shooting is also combated by the inclusion of two UD lenses, ensuring
optimum image quality and corner-to-corner detail.
Designed for use in digital photography, Canon's patented lens element coating
helps minimize the ghosting and flare caused by internal reflections. By
eliminating the cause, the coating reduces reflections and helps to deliver
crisp, clear images.
The EF 24mm f/1.4L II USMs near-silent Ultra Sonic Motor (USM) provides
super-fast auto-focusing with full-time manual override. The floating internal
focus system also helps maintain high image quality throughout the focal range.
Canon lenses are built to withstand regular use in the most testing
environments. Weather and dust seals provide added protection, and a lens hood
and pouch are also included in the package.
Environmentally friendly lead-free glass is used throughout the construction of
the EF 24mm f/1.4L II USM.
