"Adapter" - sometimes but not always - bundled with the EOS R and EOS RP. "Adapter with lens control ring" - never seen this as part of a ready-made bundle. Seems to be popular for the extra functionality. The other two allow you to use drop-in filters. Again, never seen either as a ready-made bundle with the R or RP. Harry Potter and the curse of the multi-option listing. **Q: Will this work with lenses from my Canon 7D please ?** A: The Canon 7D uses EF lenses, so any lens you have for the 7D can be mounted to RF moj t with this adapter **Q: Is this adapter weather sealed?** A: According to Canon, yes they are. Also dust sealed when connected. The Canon version us beautifully flat and forms a perfect seal. I have 3 R adapters for use with EF lenses on the R . I believe they also fit the smaller RP too. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Brilliant quality *by R***E on 3 October 2025* The quality is really good don't mind paying more for quality like this solid works good no issues yet helps make My r50 look bigger and helps balance it up with it being a small camera,yes worth the extra dosh you'll not b disappointed if you get one good stuff thanks cannon ### ⭐⭐⭐⭐⭐ Works a treat *by N***S on 3 October 2024* Hello...i've had this adapter for a while now and it works a treat with my EF lenses, primes and zoomy ones.
