Canon rf 15 30mm f 4 5 6 3 is stm vs canon 15 35mm f 2 8?

I don't have a page on this site for the Canon 15-35mm f/2.8, so I can't compare the two on specs or price. What I can tell you is how the Canon RF 15-30mm f/4.5-6.3 IS STM works. It's a full frame zoom with image stabilisation and autofocus, and it frames 15-30mm on full frame. On APS-C it frames like 24-48mm.

Its aperture is the main limit. It's f/4.5 at the wide end and gets darker to f/6.3 as you zoom in. Compared with an f/2.8 zoom, that's roughly a stop and a half darker at 15mm and over two stops darker at 30mm. A brighter lens gives you faster shutter speeds indoors and more background blur. The Lenses guide explains why constant-aperture zooms are worth the extra cost.

If you shoot mostly landscapes in good light, the 15-30mm is a sensible, light choice. Check the landscape guide to see what suits your subjects.
