Opticron Universal Smartphone Mount USM-2

The Opticron USM-2 is a universal smartphone mount that attaches your phone to any spotting scope, binocular, or monocular eyepiece for digiscoping — capturing photos and video of distant wildlife through your optics.

The spring-loaded clamp fits virtually any smartphone (up to 95mm wide) and centres the phone camera over the eyepiece for quick, aligned shooting. An adjustable eyepiece clamp fits eyecups from 22mm to 65mm diameter. Lightweight aluminium construction with soft rubber contact points to protect both phone and optics. No phone-specific adapter needed.
