Canon EF 11-24mm f/4L won the “Best Professional DSLR Lens“ award at 2015 Technical Image Press Association awards (TIPA). It provides users with access to the “widest angle of view5 yet achieved for a rectilinear full-frame DSLR zoom lens.” In addition to boasting an impressive minimum focal length of 11 mm, the lens makes possible “minimally distorted images throughout its range.”
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.
Conclusion from DxOMark:
While traditionally strong in its telephoto lineup, Canon has always been rather weak in offering a range of ultra-wide-angle lenses. When introduced a few years ago, the EF 8-15mm f4L USM Fisheye zoom helped redress the balance, but it didn’t go far enough. Now with this new lens, Canon has proved it can compete with its long-term rival Nikon as well as with new challengers, such as Sigma, who offer some very specialized models at accessible prices. Sure, the EF 11-24mm f4L USM lacks the fast f2.8 aperture of the Nikon, but Canon traded that for wider coverage and didn’t make any concessions with image quality. Even the price is relatively accessible.
