Vantrue 40mm CPL Filter for E-Series Dash Cams

This 40mm circular polariser is built for the Vantrue E1, E1 Lite, E2 and E3 front lenses. It cuts windscreen glare and surface reflections while lifting contrast and saturation. Neutral colour rendition is preserved so footage stays true to the scene. The filter will not fit any other Vantrue dash-cam models.

Polariser Limits on a Fixed Wide-Angle Lens

A circular polariser only works when the light source sits at an angle to the lens axis. Direct sunrise or sunset glare straight ahead cannot be fully removed by rotation. The 40mm thread matches the listed cameras but excludes every other Vantrue unit. No electronic adjustment is possible; the filter must be turned by hand for each lighting change.

CNC Aluminium Frame with 5.5mm Rim

The ring is machined from aluminium alloy with a knurled non-slip edge for quick fitting and removal. Its 5.5mm slim profile keeps the wide-angle view free of corner vignetting. Multi-resistant coating repels water, oil, fingerprints and static while protecting the glass from scratches during daily handling.
