Thought I’d share this. I used a Canon 90 degree view finder on my sold 7D. Really liked using it. When I got my R50 couple weeks ago i was really disappointed that I couldn’t use it on the 50 and Canon doesn’t make one or isn’t anyplace to mount one. Probably because the video screen is able to be tilted any angle. Determined I came up with a way to use the angle finder on the 50. Made a bracket out of aluminum and use the flash shoe bracket to hold it in place. Seems to be working as I want with a slight amount of vignetting in the corners of the cameras view finder. I can live with that
