Features: Bring your high-resolution video to the next level with the all-in-one 5pc professional filter kit from SSE. The circular polarizing filter (cpl) helps enhance aerial videos by reducing the amount of light reflecting off the ground, sky, or water. Removing this reflecting light allows the phantom 4 to capture beautifully saturated colors and improves contrast. The ultraviolet filter (uv) delivers added lens protection and increases overexposure in bright conditions by blocking UV light. The variable nd2-nd400 filter allows you to have more control of the camera's aperture, exposure time and sensor sensitivity settings. Helps improve video quality by introducing a natural motion blur for smoother motion in video in bright daylight situations. Simply turn the filter's exterior ring to access any of the nd2 - nd400 settings without wasting time changing or adding filters.
