Tilta Adjustable Cold Shoe Phone Mounting Bracket 
Tilta's Adjustable Cold Shoe Phone Mounting Bracket, in tactical gray, allows you to attach your smartphone directly to your camera hot shoe or a camera cage shoe mount. It's height-adjustable to support smartphones up to 3.6", and it provides tension-based tilt adjustment to let you set your phone to the desired angle on the fly without having to tighten any knobs. It also offers a shoe mount on top for attaching additional accessories, such as an LED light or microphone. The cold shoe on the bottom is secured tool-free via a built-in thumbwheel, letting you efficiently attach and remove the bracket. The inside wall of the phone holder is rubber-padded, to safely support your phone without scratching.
