Both records are reviewed against the manufacturers' sources; sources last checked 2026-10-14. Informational only: confirm with the manufacturer before buying.
Why
- ✓ Canon RF-S (APS-C RF lenses) works where Canon RF mount is expected.
Good to know
- RF-S (APS-C) lenses mount on full-frame EOS R bodies, which automatically switch to 1.6x crop mode.
- EF and EF-S lenses only work on RF bodies through a Canon Mount Adapter EF-EOS R (or the Control Ring / Drop-In Filter versions); they do not mount directly.
- EF-M lenses and CN-E cinema lenses cannot be used via the EF-EOS R adapter.
- EOS R50 excludes the RF 5.2mm F2.8L DUAL FISHEYE lens.
- On full-frame EOS R bodies, RF-S lenses automatically enable 1.6x crop mode.
