SANDMARC Aerial Filter: ND4, ND8 and Polarizer Filter Set for DJI Phantom 4, Phantom 3 Professional and Advanced &ndash; 3 Pack DYNAMIC FOOTAGE: By reducing light coming to your DJI sensor, increasing your control on exposure (ND), managing reflections and suppressing glare (polarizer), SANDMARC Aerial Filters allow you to capture footage that needs little to no post production. ULTRA LIGHTWEIGHT: The weight of the filters is critical especially when using filters for DJI. In order to achieve this, we use aluminum frame material providing the lightest yet most durable finish to our filters. SUPERIOR MATERIALS: When using filters for your photography, it is important to ensure that your DJI does not lose its picture sharpness and quality. To ensure that, we use industrial grade and meticulous multi-coating process to make our filter glass materials. MULTI-COATED: For photography, uncoated filters are more likely to set up lens flare. Multi-coating provides a refined quality with further enhanced and accurate transmission of light and colors. INCLUDES: Polarizer, ND4 (2-Stop ND), ND8 (3-Stop ND) Filters and Filter Case.
