This Slim Frame Neutral Density Glass Filter from Polar Pro is a snap-on filter that is compatible with the GoPro HERO3 camera's waterproof or skeleton housing. It is designed to produce smoother motion in fast-action situations. The neutral density filter reduces the amount of light hitting the lens by 3 stops, which causes the HERO3 to slow down its normally high shutter speed to compensate for the light loss. The result is more motion blur on moving subjects and less noticeable rolling shutter effects. This is particularly useful in motorsport, aviation, or quadcopter applications.
The filter is constructed from scratch resistant glass for increased protection and maintained image sharpness. The snap-on design also allows for quick installation and removal of the filter. A tether cord and microfiber storage bag come included.
