I have a Canon SX50HS, it's a bridge type camera. I bought a FlashRing - Macro (model: Aputure Amaran Halo AHL-C60) It came with many adapters, unfortunately they were all to reflex type cameras. So I design this adapter... Works like a charm! ;)

I've included a step file for those who have a different camera and want to make some changes to the adapter.
