UV Filter (6 grams) The UV filter is used for lens protection during flight/crashes when you do not need any aperture/shutter control. This UV filter will also cut haze and make clouds pop a bit more. Multi-Coated UHD glass for pristine optics. CP Filter (Polarizer) (7.65 grams) The CP filter is used for reducing glare off of the ground, water and sky. This filter is especially important while flying because shooting from an elevated perspective causes the camera to pick up a lot of reflection of the ground. The polarizer helps improve color saturation in bright scenes and also improve contrast. In addition to glare reduction the Polarizer will make the sky a deeper blue and allow clouds to pop. Multi-Coated UHD glass for pristine optics. ND8 Filter (3-stop) (6 grams) The ND8 filter reduces 3 f-stops of light. Generally speaking, trying to hold aperture at f2.8 or f5.6 the ND8 filter would be used on a cloudy to partly cloudy day to knock shutter down to 1/60th. Multi-Coated UHD glass for pristine optics.
