Canon EOS R50 - compatible ring flashes

[Pedrolamdds]

Hello! I’m a beginner photographer looking to document my surgical cases in dentistry. I’ve purchased both a EOS R50 and an EOS R10 and needed ring flashes for both of them. A Godox alternative worked and synced very easily on the R10, however the R50 wasn’t able to. 
Before I buy a second ring flash, are there any affordable alternatives for a good Ring Flash for macro photography that is fully compatible with the R50 system? Thanks in advanced!

Are you photographing your patients? Wouldn't you need written permission from them? Others might comment here.

The big difference between the EOS R50 and EOS R10 is that the EOS R50 has a flash hotshoe that only contains the contacts for the multifunction accessory shoe, not the older legacy connections for flashes. So a flash that triggers on the EOS R10 won't necessarily work on the EOS R50. 

Canon offers a multi-function accessory shoe adapter AD-E1 that slides in to the multi-function accessory shoe and provides the standard connections that are found in most other cameras.

Before you seek out an alternative flash I would get the multifunction accessory shoe adapter AD-E1.
