Designed for the Osmo Action 5 Pro and 4, the SmallRig Attachable Light Pollution Reduction Filter 5837 snaps over the camera's lens, so you can turn the camera on and start shooting instantly. The star cross filter lets you add a crisp six-point star to point light sources, maintaining native image clarity and sharpness while expanding creative control. It stays clean, resists scratches and handles rough handling well thanks to B270 optical glass with multi-layer coatings.
