These adapters are either hard to find, have a long back-order whether it be from Amazon, B&H Photo, Adorama, 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. 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).
We've compiled a list of brands and where you can purchase them. 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 know...you may end up liking the aftermarket ones and save some money.
If you find any additional adapters that we may have missed, please let us know.
