Digital Camera World Verdict

Canon wants to set high standards with its RF lenses, and the RF 15-35mm f/2.8L IS USM largely meets our expectations. It combines fast focusing, adequate sharpness across the frame and no visible distortion when looking at real world images. With its fast, constant f/2.8 aperture and 5-stop Image Stabilizer, it’s one of the three key lenses any pro will look for in a professional camera system.

The wait for some pro-level constant-aperture f/2.8 lenses for the Canon EOS R system has been quite a long one, but it looks like things are moving now. The Canon RF 15-35mm f/2.8L IS USM is the first of the ‘holy trinity’ lenses for the EOS R, which also comprises the Canon RF 24-70mm f/2.8L IS USM and the upcoming Canon RF 70-200mm f/2.8L IS USM.

This new lens is big, and it’s expensive, but that’s par for the course with Canon’s L-series lenses. Once you take that on board, whether you’re an existing Canon EOS R  owner or somebody who’s been waiting for a premium wide-angle lens before jumping aboard the system, we don’t think you’ll be disappointed. We already rate the EOS R (and EOS RP) amongst the best Canon cameras, but they're going to need the best Canon RF lenses too.
