Ultra-wide L-series zoom for full-frame DSLR

The Canon EF 11-24mm f/4L USM is an L-series ultra-wide zoom lens built for full-frame EOS DSLR cameras. Its focal range begins at 11mm and extends to 24mm with a constant f/4 maximum aperture. One Super UD element and one UD element work with four aspherical elements to control chromatic aberration and distortion across the frame. Subwavelength and Air Sphere coatings suppress flare and ghosting for accurate colour and contrast.

Optical performance at constant aperture

The lens maintains f/4 throughout the zoom range, so exposure stays consistent when reframing. Inner focusing driven by a ring-type ultrasonic motor and a high-speed CPU delivers fast, quiet autofocus without extending the barrel. Full-time manual focus allows immediate manual override while the camera remains in AF mode. Closest focusing distance is 0.28m, enabling close-up perspectives at the widest angles.

Mount and format compatibility check

This lens uses the Canon EF mount and covers the full-frame image circle. It is designed for EOS DSLR bodies with an EF mount; mirrorless RF-mount cameras require an adapter. Crop-sensor EF-S bodies will see a narrower field of view equivalent to a longer focal length. Verify that your camera accepts EF lenses and that the 11mm starting width suits your intended architectural or panoramic work.
