Canon RF 15-35mm F2.8L IS USM Review

Gordon from CameraLabs got his hands on a Canon RF 15-35mm F2.8L IS USM and of course, reviewed it. The Canon RF 15-35mm F2.8L IS USM is the ultra-wide professional F2.8 "L" lens for the RF mount. Gordon tested this lens on the 30MP EOS R. It will be interesting to see how all the professional lenses fare on the R5 with 45MP, and what we hope will be the R5s which should be well over 50MP.

The key features of the Canon RF 15-35mm F2.8L IS USM;

RF-Mount Lens/Full-Frame Format
Aperture Range: f/2.8 to f/22
Three Aspherical Elements
Two Ultra-Low Dispersion Elements

Gordon's verdict on the lens;

The Canon RF 15-35mm f2.8L is the first ultra-wide lens in the native EOS R mount, and as such a key model for the system. Like other high-end RF lenses, it performs very well whether you’re shooting near or far, taking photos or filming video.

Unsurprisingly its biggest rival is Canon’s most recent EF version, in this case the excellent EF 16-35mm f2.8L Mark III. The new RF version is almost identical in size, similar in weight and in the majority of my tests also delivered very close results. It does however differ in two key respects: first it zooms a little wider at the short-end while maintaining the same coverage at 35mm, thereby delivering a slightly broader range overall. Secondly it now includes optical stabilisation which, while modest in my tests, still allowed me to handhold shutter speeds two and a half stops slower than without. It’s also beneficial for video, although Canon’s digital movie stabilisation can also do a good job with non-IS lenses like the EF 16-35mm.
