I've been wanting to get an L bracket for my R, but don't want to spend a lot for an accessory like that. I'm a member of a Canon R Facebook group and one of the members mentioned this one that he got from ebay for $17: https://www.ebay.com/itm/Alumi-Came...419545?hash=item2aea976fd9:g:fNkAAOSwU0Vdy2Vq
He also mentions an Arca Swiss adapter he found to use with it. Hope this helps somebody.
