Review on TK-3 Aluminum DSLR Camera Cage Kit for Canon 5D Mark II 7D 70D 60D: Enhance Your Filmmaking with Versatile Mounting Solution! by Bret Wong

I have a TK-3 cage with a handle and a pole. Very beautiful and durable. But when you added the matte box I found my Canon 70D didn't work together. The Canon 70D sets the cage mount low and doesn't center the matte box, and the underside of the matte box obscures the view of the lens. I had to modify and purchase an additional camera tripod mount and plate to get it working. So the moral of the story is, make sure your camera works before you buy it.
