Freewell Luna Ultra ND32/PL ND/PL Filter for Insta360 GO 3

Cut light by 5 stops while taming glare and reflections with the Freewell Luna Ultra ND32/PL Filter for Insta360 GO 3. Built around German Schott optical glass with a 16-layer multi-coating, this magnetic snap-on filter pairs an ND32 neutral density element with a circular polarizer to give you precise exposure control and richer, more saturated footage in bright daylight.

Overview

The Freewell Luna Ultra ND32/PL is a hybrid ND/PL filter designed specifically for the Insta360 GO 3 action camera. It combines a 5-stop neutral density filter (ND32) with a polarizing layer, reducing light transmission to 1/32 while cutting through haze and reflections. The result is smoother motion blur in video, better long-exposure stills, and colors that pop without post-processing.

What stands out

• ND32 + polarizer in one ultra-slim filter: 5-stop light reduction and glare control without stacking multiple filters.
• German Schott optical glass with 16-layer multi-coating: waterproof, scratch-resistant, oil-proof, and anti-reflective for lasting clarity.
• Aircraft-grade aluminum frame: lightweight and durable, engineered to be gimbal-safe for the GO 3's stabilization.
• Magnetic snap-on mounting: attaches instantly and securely, no threading or tools required.
• True-to-life color reproduction: neutral color profile preserves natural tones while enhancing saturation and contrast.
