Freewell filter pre Insta360 Luna Ultra ND16/PL

Take control of exposure and eliminate unwanted reflections with the Freewell ND16/PL filter, purpose-built for the Insta360 Luna Ultra. This high-performance filter combines a neutral density rating of ND16 with a circular polarizer, giving you the equivalent of 4 stops of light reduction while boosting contrast and color saturation straight out of the camera.

Advantages

Designed to capture professional-looking footage, this ND/PL filter allows you to shoot at wider apertures or slower shutter speeds in bright sunlight, bringing cinematic motion blur to action scenes. The integrated circular polarizer cuts through reflective surfaces — water, glass, and foliage — reducing glare and deepening blues and greens. Multi-coated optical glass ensures crystal-clear image quality, while the aluminum alloy frame keeps the filter lightweight yet durable for on-the-go creators.

Suitable for

• Insta360 X4 action camera users shooting in bright outdoor conditions
• Vloggers and travel filmmakers who want to reduce glare and improve color
• Creators producing video with a natural motion-blur effect
• Photographers seeking combined ND and polarizing control in a single filter
