The Canon EF 11-24mm f/4L USM Lens is a highly versatile wide-angle zoom lens designed for full-frame EOS DSLRs, belonging to Canon’s renowned L-series. With its advanced optical design and constant f/4 maximum aperture, this lens delivers exceptional image quality.
The lens incorporates one Super UD (Ultra-Low Dispersion) element and one UD element, effectively minimizing chromatic aberrations for improved clarity. Additionally, four aspherical elements are utilized to reduce distortions and maintain edge-to-edge sharpness and illumination. To enhance contrast and color accuracy, both SWC (Subwavelength Structure Coating) and ASC (Air Sphere Coating) coatings have been applied to the lens elements, minimizing lens flare and ghosting.
Designed for landscape and architectural photography, this lens offers a wide range of perspectives, from ultra-wide to wide-angle. It excels in capturing expansive scenes with its sophisticated optical components and ensures intuitive handling.
The lens features a ring-type Ultrasonic Motor for fast, smooth, and nearly silent autofocus performance. Full-time manual focus operation is available, allowing for precise adjustments even when autofocus is engaged. The lens also employs an internal focusing design.
Built to withstand various shooting conditions, the lens is both water and dust-resistant. Furthermore, fluorine coatings have been applied to the front and rear elements, providing protection against fingerprints and smudges, thus preserving image quality.
