Is the canon rf 15 35mm f 2 8l is usm good on aps c?

Yes, it works on APS-C, though it's really a full-frame lens doing a crop job. On a Canon APS-C body it frames like a 24-56mm, a handy everyday range, and f/2.8 gives about the depth of field of f/4.5. It's stabilised and autofocuses, and it fits APS-C bodies such as the Canon EOS R7, Canon EOS R10 and Canon EOS R50.

My honest take: on APS-C it's a big, heavy lens for what you get. If you mostly shoot on a crop body, a lighter standard zoom or a fast prime will probably suit you better. Start with Lenses, and check sensor sizes to see how the crop changes your framing. If wide landscapes are your thing, this is still a strong choice; see landscape.
