With the release of Canon's R-series full-frame mirrorless cameras, 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:

At the time of this post, 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 a Canon version or if you feel the need to get OEM.

You never may end up liking the aftermarket ones and saving 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. Price may vary from listed pricing. All pricing is listed in USD.

The Benro Aureole is a detachable drop-in filter mount adapter that features a filter loading system. The new adapter / filter holder is available in two variants: one (RC1) adapts Canon EF glass to an RF mount camera such as the EOS R5, the other (RE1) allows the use of Canon EF glass on a Sony E camera such as the popular a7S III. The trick to this adapter is certainly that it can accommodate up to two drop-in filters. Both square and circular filters are supported. Small thumbwheels can be used to adjust the filters, e.g. to set the desired strength of a gradient ND filter or to adjust a circular polarizing filter.
