The On Glass Spotting Scope Adapter is a versatile and affordable spotting scope phone adapter that is perfect for capturing stunning images or videos of animals or targets through just about any optic. Watch the video below of us interviewing the inventor and owner of the On Glass system.
The On Glass Spotting Scope Adapter is a great choice for those looking for an affordable and versatile spotting scope phone adapter. Its strong rare-earth magnets create an incredibly stable platform, while its construction makes it lightweight yet sturdy. If you get a new phone you only need a small inexpensive part to update your new phone.

With its strong rare-earth magnets, the On Glass system creates an incredibly stable platform, requiring only a super thin plastic plate adhered to the phone to secure the device to the optic. The piece that attaches to your phone is small, lightweight, and works with any case. It also still fits in your pocket, unlike many of the other options on the market. The On Glass Adapter is compatible with spotting scopes, binoculars, and night vision like a PVS 14. It is also tough, and even if you were to break it, there’s a warranty.

That is very interesting but I already have a Galaxy S-22 Ultra in a magnetic case. This thing has 100 times zoom and very good low light capabilities built in. With the magnetic case it’s very easy to attach to a wide variety of stand alone or handheld tripods.What I’m looking for is a high quality telephoto lens with 20-25+ power zoom that doesn’t weigh much and take up a lot of space like a spotting scope would, and ISN’T MADE IN china that I can attach to the phone and leave everything but a tripod at home.
