Manage multiple light intensities to achieve a more properly exposed mobile photo or video when using the MagEase Magnetic Smartphone VND Filter Kit with 52mm Adapter from SmallRig. The adapter slides over your phone's lens and manually screws into place. The adapter ring can accept any 52mm camera filter or you can magnetically click the included VND filter to the adapter. Made from German Schott B270i HD glass, the large diameter and ultra-thin filter is made to deliver crystal clear results with no vignetting. Simply twist the filter to dial in precise light reduction from 1-5 stops, mimicking the effect of ND2 to ND32 filters.
