Is the canon rf s 10 18mm f 4 5 6 3 is stm worth it?

Yes, if you shoot an APS-C Canon RF body and want wide. At 10-18mm it frames like 16-29mm on full frame, which suits big skies, interiors and tight spaces. It's stabilised, so it helps when the light drops.

The catch is the aperture. At f/4.5-6.3 it's slow, and it gets darker as you zoom in. For landscapes you'll usually stop down anyway, so that matters less. If you want low light or shallow depth of field, look elsewhere.

It fits APS-C bodies like the Canon EOS R7, Canon EOS R10 and Canon EOS R50. Full-frame bodies such as the Canon EOS R6 Mark II can use it, but only in crop mode, so I wouldn't buy it for one.

For how wide zooms get used, see the landscape guide. The full specs are on the lens page.
