HOW IT HELPS The Standard Day 4 Pack filters for Mavic Air from Freewell are designed to provide excellent quality images and footage in daylight. This pack contains those 4 essential drone camera lens filters that expert aerial photographers know are frequently required when you want to capture stunning professional quality commercial aerial videos. These filters work to give perfect and crystal clear images in cloudy to bright sunny lighting conditions outdoors. The ND (Neutral Density) filters are designed to cut the amount of light by 2x f-stops hitting the camera sensor, which slows down the cameras shutter speed. The CPL (Circular Polarized Lens) filter is helpful in preventing unwanted glare from natural reflective surfaces, such as windows and water bodies, to spoil your image quality. ND4 for Mavic Air The Freewell ND4 filter for DJI Mavic Air mini drone is designed to reduce the amount of light entering the camera lens by 2 f-stops. It helps to slow down the shutter speed considerably and is ideal for use in cloudy daylight conditions. The Freewell ND4 filter is an excellent choice for use on overcast or medium cloudy days to capture stunningly clear pictures and videos. ND8 for Mavic Air The Freewell ND8 filter is designed to cut light by 3 f-stops as it enters the camera lens. It helps to capture crystal-clear footage and images on partly cloudy days. With the Freewell ND filter, you can also prevent the undesired jello effect, which is often seen when filming objects in motion. It helps to give such footage a natural blur motion. ND16 for Mavic Air The Freewell ND16 filter is effective for cutting the amount of light hitting the camera sensor by 4 f-stops. It helps to capture cinema-quality footage on normal sunny days. CPL for Mavic Air The Freewell CPL filter is designed to get sharp images when shooting outdoors in sunny conditions.
