Use your smartphone for mobile photography or as an external monitor with this Metal Phone Holder with Cold Shoe Mount from SmallRig. The combo 1/4"-20 and cold shoe plate base let you mount your phone to the top of a camera or a tripod. The spring-loaded clamp with protective padding can open to accommodate 2.5 to 3.5" wide phones. A hinge behind the clamp and at the base allow for two points of forward-and-back tilt to achieve the perfect viewing or shooting angle. You can also orient the phone in a portrait or landscape position with 360° of rotation.
