The VPA 2 Variable Phone Adapter enables you to capture photos and videos on your smartphone through your Swarovski binoculars or spotting scope. Supporting smartphones from 2.3 to 3.3" wide, the adapter is made to be light for easy packing and carrying on the trail, yet rugged enough to stand up to the rigors of daily use. The near-universal fit allows access to most of your phone's controls and can be adjusted for just about any camera lens placement. This is the phone adapter only; compatible eyepiece rings are available separately based on the Swarovski binocular or spotting scope model you want to digiscope through.
