Canon EF 11-24mm f/4L USM
A truly versatile wide-angle zoom featuring an advanced optical design and constant f/4 maximum aperture,
the Canon EF 11-24mm f/4L USM Lens is a member of the esteemed L-series of lenses designed for full-frame EOS DSLRs. One Super UD element and one UD element offer a significant reduction in chromatic aberrations while four aspherical elements help to minimize distortions throughout the zoom range and provide consistent edge-to-edge sharpness and illumination.
Both SWC and ASC coatings have been applied to the elements in order to reduce lens flare and ghosting for increased contrast and color accuracy.
Ideally suited for landscape and architectural photography,
this lens covers ultra-wide to wide-angle perspectives and backs up its versatile zoom range
with sophisticated optical components and intuitive handling.
In regard to focusing performance, a ring-type Ultrasonic Motor offers fast, smooth,
and near-silent autofocus,
which is further benefitted by full-time manual focus operation and an internal focusing design.
The lens is both water and dust-resistant,
and fluorine coatings have also been applied to the front
and rear elements to protect against fingerprints and smudges from affecting image quality.
To experience the ultimate in wide-angle photography,
the EF 11-24mm f/4L USM brings L-series construction and optics to the widest zoom lens Canon has ever made.
With an expansive wide-angle range of 11-24mm, this is an ideal lens for landscapes, interior shots, and unique perspectives on subjects close and far.
Its new optical design features Super UD and UD lenses that correct chromatic aberration.
Four aspheric lens elements help to minimize distortion from the center of the image to the periphery and throughout the zoom range.
