FotodioX 77mm Ninja Filter Adapter Kit

Compatible with most iOS and Android devices, the 77mm Ninja Filter Adapter Kit from FotodioX lets you use virtually any filter with your smartphone or tablet. With a 77mm filter thread, the advantage of being able to use a larger filter is that it will not vignette when used with an extremely wide-angle lens. The adapter opening is also large enough to accommodate the multiple lenses that smart devices have, without needing make adjustments when switching lenses.
