Neewer FL40 Pack ND & CPL Filter Set For insta360 Ace Pro
Product Description
The Neewer FL-40 ND & CPL Filter Set is a four-piece optical filter collection engineered specifically for the Insta360 Ace Pro action camera. This kit includes a circular polarising filter and three neutral density filters (ND16, ND32, and ND64) that give you precise control over exposure and light management in challenging outdoor conditions. Each filter features multi-coated HD optical glass in an ultra-slim aluminium frame that adds just 4.5g to your camera setup, maintaining the compact profile essential for action sports and POV filming.
This filter set is essential for action camera users, outdoor filmmakers, adventure content creators, and anyone shooting in bright daylight conditions where the Ace Pro's fixed aperture and fast shutter speeds can lead to overexposed, washed-out footage. It's particularly valuable for capturing smooth motion in bright environments, shooting near water or reflective surfaces, and maintaining proper exposure when filming fast-paced activities like cycling, skiing, surfing, or motorsports.
Action cameras excel at capturing movement, but their small sensors and fixed apertures struggle with bright sunlight, often producing footage with blown highlights, excessive contrast, and unnatural motion blur. The ND filters solve this by reducing light entering the lens without affecting colour accuracy, allowing you to maintain cinematic shutter speeds for smooth, natural motion blur. The CPL filter tackles another common problem by eliminating glare and reflections from water, snow, glass, and other reflective surfaces that can ruin otherwise perfect shots.
The three ND filters provide progressive light reduction: ND16 cuts light by four stops (ideal for partly cloudy days), ND32 reduces five stops (perfect for bright sunny conditions), and ND64 blocks six stops (essential for intense sunlight or snow environments). The CPL filter rotates to adjust polarisation strength, letting you dial in exactly how much glare reduction you need. Multi-layer coatings on both sides of the optical glass repel water, resist scratches, shed oil from fingerprints, and minimise internal reflections that could degrade image quality. The precision CNC-machined frames attach securely without tools and won't vignette or interfere with your camera's field of view.

Common Dos and Don'ts
✓ Start with ND16 on partly cloudy days and progress to stronger filters as sunlight intensifies
✓ Rotate the CPL filter whilst watching your camera's screen to find the sweet spot for glare reduction
✓ Use ND64 when filming snow sports or beach activities where reflected light is exceptionally bright
✓ Store filters in the provided case between uses to protect the coated glass surfaces
✓ Clean filters with the included microfibre cloth using gentle circular motions, never your shirt or rough fabrics
✗ Leave filters attached when not needed, as they reduce light and can cause underexposure in dimmer conditions
✗ Stack multiple ND filters together, as this can cause vignetting and image quality degradation
✗ Touch the glass surfaces with your fingers - even with oil-proof coating, fingerprints still affect image quality
✗ Force filters onto the camera if they don't align smoothly, as cross-threading can damage the mounting mechanism
✗ Assume the CPL filter works like sunglasses - it selectively reduces polarised light, not overall brightness, so you'll still need ND filters for exposure control
