Use any smartphone make and model with the SMART BRACKET. Easily adjust the smart bracket to fit over your standard or telephoto lens. Must use with an existing adapter. This will not work by itself. Works with our GEN 2 universal adapter (gen 2 adapters have the OD thread and ID thread). The match ring must be used on the older Gen 1 optic adapters. Machined out of aircraft quality aluminum, anodized in earth brown color. Super easy to adjust and use.
