Review on SmallRig CCC2803 Camera Cage for Canon EOS R with Built-in Cold Shoe and Anti-Twist Design by Sean Bouchard

This is a great cage with lots of useful features and points to build on. It's amazingly comfortable in your hand while still giving you access to everything you could possibly need. One annoying design I don't like is that you can't sit on it with anything other than a pancake lens without falling off. Not a big deal but definitely annoying as I don't want to always put it on a tripod when not in use.
