Can I adapt the sigma 18 200mm f 3 5 6 3 dc macro os hsm contemporary to canon rf?

The site doesn't cover Canon RF for this lens. The Sigma 18-200mm f/3.5-6.3 DC Macro OS HSM Contemporary is listed only for Canon EF, Nikon F and Pentax K, and it's made for APS-C sensors. I can't tell you from here whether an adapter would work or how it would behave on an RF body.

If you want it working on Canon, it's listed for APS-C Canon EF bodies such as the Canon EOS 90D and the Canon EOS 850D. Those are the picks I'd start with.

For more on adapting lenses in general, see the adapters section on the lenses page. It's about old manual-focus lenses, so it doesn't settle this question.
