The Canon EF 11-24mm f/4L USM is an ultra-wide DSLR zoom lens, but it's got some strong competition

Digital Camera World Verdict

For a rectilinear rather than fisheye lens, this full-frame compatible zoom takes viewing angles to the extreme. The price tag is similarly large but Canon’s EF 11-24mm is something of an engineering feat and has impeccable build quality, along with excellent all-round performance. At the end of the day though, the competing Sigma 12-24mm f/4L DG HSM almost matches the Canon for viewing width, delivers superb image quality and only costs about half as much to buy, making the Canon look relatively poor value.

The Canon EF 11-24mm f/4L USM launched as the world’s widest-angle rectilinear zoom lens, overtaking the Sigma 12-24mm f/4 DG HSM | A by a single millimeter in its shortest focal length. The 11mm focal length delivers a monstrous 126-degree viewing angle, measured on the horizontal of the image frame. It’s only marginally bigger and heavier than Sigma’s 12-24mm ‘Art’ lens, which almost matches the Canon with a maximum viewing angle of 122 degrees.
