Product Description
Revolutionary Ultra-Wide Perspective
The Canon EF 11-24mm f/4L USM delivers an unprecedented 11mm starting focal length, making it the widest rectilinear zoom lens in Canon's lineup. This L-series optic captures expansive landscapes, dramatic architecture, and spacious interiors with remarkable edge-to-edge sharpness. The constant f/4 maximum aperture ensures consistent exposure throughout the entire 11-24mm zoom range, while the minimum focusing distance of 0.28m (11 inches) allows you to get remarkably close to subjects for creative compositions.
Advanced Optical Engineering
Precision-crafted with one Super UD (Ultra-Low Dispersion) element and one UD element, this lens effectively suppresses chromatic aberration across the frame. Four aspheric lens elements minimize distortion from center to edge, maintaining straight lines even at the extreme 11mm focal length. Canon's Subwavelength Coating (SWC) and Air Sphere Coating (ASC) technologies dramatically reduce flare and ghosting when shooting toward bright light sources, ensuring high contrast and color fidelity in challenging lighting conditions.
Professional Build and Performance
The rear focusing system combined with a ring-type Ultrasonic Motor (USM) provides silent, high-speed autofocus ideal for video recording and quiet environments. Full-time manual focus override allows instant manual adjustments without switching out of AF mode. The 9-blade circular aperture diaphragm produces smooth, pleasing bokeh when shooting at wider apertures. Optimized AF algorithms and a high-speed CPU ensure reliable focus tracking and accuracy across the entire zoom range.
Built for Demanding Professionals
Constructed to exacting L-series standards, this lens delivers weather-resistant durability and optical excellence. The robust all-metal construction withstands rigorous field use while maintaining precise optical alignment. Compatible with full-frame Canon EOS DSLR cameras, this lens also works seamlessly on APS-C sensor bodies, providing an effective focal length of approximately 17.6-38.4mm for versatile wide-angle coverage.
