Confirm the maker SKU, physical mounting system and verified lens front thread. A nominal size alone does not prove fit or freedom from vignetting.

Canon states this clear insert belongs in the Canon Drop-In Filter Mount Adapter EF-EOS R. It is not sized by a lens’s front-thread diameter and does not fit a standard EF-EOS R adapter without a drop-in slot.
What remains unverified
A maker’s accessory specification establishes its intended connection system. It does not guarantee no vignetting, no hood interference or fit on every lens sharing a printed diameter. Check the exact lens manual and perform a careful test.
