Perfect

Fits Perfectly . Great Mounting Options For Accessories. It's Easy To Add And Subtract Accessories, With Smallrig Offering A Great Selection. Plus, The Mounts Are Standard So It's Easy To Find Third Party Add-ons. The Addition Of The Hdmi Cable Holder Is Amazing. Never Shoot Without One Anymore. The Tool Needed To Attach And Remove The Cage Is Stored Inside The Product Itself, It's Always There For You. 10/10, Highly Recommend.

I have been looking for a cage and handle for a while, this combo was a great way to get a good deal for both.
