This cage would've been fantastic if it didn't have the one MAJOR problem with it. It doesn't hold your camera correctly, it has a slot at the bottom where the thumb screw can slide back and forth regardless of how tight you screw it. This not only damaged my camera but becomes another thing to worry about on set.
When shooting photos and holding the camera like a camera, the cage will stay stationary as you struggle to keep the camera from moving around as you trigger the shutter with the button.
This is an absolute deal breaker for me. I hate having my things damaged, I hate unnecessary stresses on set.
I would rate it a 4/5 star product, but because the thumb screw is stupid, I'm going to give it only 2/5.
