toney20004 years ago000I have an EOS RP housing. Will the lens fit with this or do I need an adapter? I'm a bit confused with EF and RF mounts.Show in original language (German)Anonymous4 years ago+110 Helpful answerFor an RP, I would buy RF lenses and not old EF lenses. EF, however, fits RF with an adapter. RF, however, does not fit EF. That's how it looks. Native lenses are always better. Adapters are stopgap solutions.Show in original language (German)Commentindependenttrs4 years ago+220Oder Du verwendest das folgende Objektiv Canon RF 50mm F1.8 STMCommenttoney20004 years ago+110Thank you for the quick answer! =DShow in original language (German)Commentindependenttrs4 years ago+110You need an adapter.
