Your iPhone is already capable of capturing amazing photos and video. With the SANDMARC Hybrid Filter, you can do even more. It is a polarized ND filter that reduces glares and reflections for clearer skies and more transparent bodies of water. It is made with a multi-coated and anti-reflective glass.
These filters are compatible with SANDMARC iPhone lenses. You can easily attach the filter to your phone camera with the clip-on mount provided. To adjust the polarization levels, simply rotate the front piece.
