 - 9/15/21: Added ProMaster adapter 

With the release of Canon's new full-frame mirrorless cameras, the EOS R5 and R6, the EF-RF lens mount adapters extend the range of compatible lenses designed for attaching any EF or EF-S-mount lens to the EOS R-Series mirrorless digital camera. Canon offers four different version of the adapters:
These adapters are either hard to find, have a long back-order whether it be from Amazon US, Amazon CA, Amazon UKB&H PhotoAdorama, Canon's online store or even price gouged on eBay.

However, if you are in need of an EF/S-RF lens mount adapter immediately for a project or vacation, there are other alternatives from 3rd party manufacturers. We've compiled a list of brands and where you can purchase them. The adapters retains full auto-focus and image stabilization capabilities and contains no optical components, thereby maintaining the original optical quality of the mounted lens. The only difference between OEM and 3rd party is the material quality and added lens/tripod collar (if applicable). They don't break the bank like the Canon or the price gouging from 2nd hand markets but it will hold you over until you're able to find an Canon version or if you feel the need to get OEM.

You never may end up liking the aftermarket ones and save some money.

We’re continuously working to improve this list by adding new adapters and removing the ones that are no longer in production. Please if you find any new or missing adapters that will need to be on the list.

Filmmakers are now able to mitigate most of the 4K video crop factor of EOS R (1.75x) and EOS RP (1.63x) and reduce it to 1.24x and 1.15x respectively. The field of view is now much closer to still photo mode. This Speed Booster is not intended for still photography but will work if the camera is configured to APS-C mode. 60p FHD video does not work at all.

Our filters are thickness matched to minimize focus shift, EXCEPT for the IRChrome and UV Bandpass. These two filters need to be thick by design, which can reduce macro focus range, and can reduce corner sharpness on wide-angle lenses. In our tests the effects were fairly minor, however.
