Freewell Luna Ultra ND8/PL Filter for Insta360 GO 3 – Neutral Density & Polarizer, Magnetic Mount

The Freewell Luna Ultra ND8/PL Filter is a dual-function lens accessory specifically engineered for the Insta360 GO 3 action camera. This compact magnetic filter combines a 3-stop neutral density (ND) filter with a circular polarizer (PL) in a single, ultra-lightweight unit. Whether you are shooting video or stills, this filter gives you creative control over exposure and glare, making it an essential tool for content creators who demand professional image quality on the go.

Advantages

By reducing the amount of light entering the lens by 8x (ND8), the ND8/PL filter allows you to use slower shutter speeds or wider apertures in bright conditions, enabling cinematic motion blur and shallow depth of field. The integrated polarizer effectively cuts through glare and reflections from water, glass, and foliage, while enriching color saturation and contrast. The 16-layer multi-coating on the German Schott B270 optical glass resists scratches, water, oil, and fingerprints, ensuring crystal-clear imagery in demanding environments. The magnetic mounting system lets you snap the filter on and off instantly, so you never miss a moment.

Recommendations

To get the most out of your Luna Ultra ND8/PL filter, use it during midday or other high-light situations to avoid overexposure. The magnetic mount is robust but always ensure the filter snaps firmly into place before recording. When not in use, store the filter in its protective case to keep the glass pristine. This filter is engineered specifically for the Insta360 GO 3 and may not fit other models; always verify compatibility before mounting.
