Here is another filter that lets you do more with your phone. The SANDMARC polarized ND filter that reduces glares and reflections for clearer skies and more transparent bodies of water. Its ND filter gives you more flexibility with shutter speed. This ND filter is made from multi-coated and anti-reflective glass and has an aluminum frame.
SANDMARC’s Hybrid Filters are compatible with iPhone lenses from the same company. To get started, secure the filter to your camera with the clip-on mount and adjust the polarization level by rotating the front piece.
