Sensei SUR-2537 Reviews
Perfect for my oddball use.
This product is the key to extending an old Pocket Cams usefulness. I epoxied one of these to my old Kodak Zi8 to adapt it for use with filters and lenses. Now I can use UV and ND filters to cut glare while expanding the field of vision with a wide angle or fisheye. This trick might even work with some phone cases depending on where the camera is.
