Camera House ProMaster Mobile Lens Kit v2.0 - Tele, Wide Macro, Fisheye
The ProMaster Mobile Lens Kit features a dual mounting system engineered to provide photographers maximum flexibility in how they attach each lens or filter. Mounting Method 1: A small thin ring, with adhesive backing, is applied to the mobile device or case, so the lens can cling magnetically. Mounting Method 2: The lens can be screwed into a small, hinged clip mount that looks like a clothespin. Open its jaw and position over the lens of the mobile device.
