Is the canon rf 15 35mm f 2 8l is usm good for landscape?

Yes, it's a good landscape lens on a full frame Canon RF body. The landscape guide calls a wide zoom around 16-35mm the classic landscape choice for big skies and strong foregrounds, and this one covers that range. It's also stabilised, which helps when you're hand-holding in low light.

The guide also points out that landscapes rarely need a fast aperture, since you'll usually shoot between f/8 and f/11. That makes the f/2.8 aperture more than you need for this job. An f/4 wide zoom is lighter and cheaper and will do the same work, so it's worth comparing before you commit.

If you go with this lens, pair it with a full frame body such as the Canon EOS R5 or Canon EOS R6. On an APS-C body, it frames more like 24-56mm, which is too tight for most landscapes, so the landscape page suggests a 10-24mm lens there instead.
