Review on SMALLRIG Canon EOS M3 and M6 Cage with Cold Shoe and NATO Rail (Not for M6 Mark II) - 2130 by Jermaine Batista

Although the description does not state it will fit the M6 Mark II, many accessories are often interchangeable between the M6 and M6 Mark II. However, this cell is not one of them. The cage essentially matches the camera's form factor. However, the cage mounting screw does not match the M6 Mark II mounting screw hole. That issue aside, the cage looked well constructed and seemed to serve its purpose quite well. I returned the SMALLRIG cage and bought a UURig cage for the M6 Mark II and it fits perfectly. So if you have an M6 Mark II and need a cage for it, you need a UURig cage as this SMALLRIG cage for the M6 will not fit your camera. UURig Cage for M6 Mark II: https://www.amazon.com/gp/product/B081CLJQ38/ The SMALLRIG cage is well made with plenty of mounting options for all your accessory needs. While I love the UURig cage for the M6 Mark II, I would like to take the SMALLRIG cage as another option for my main rig.
