M-Series | 37mm ND Filter, ND 8

Moment M-Series 37mm ND 8 Filter — steady footage for hazy mornings and shaded streets

The gist: A 3-stop ND filter suited to travel filming in bright-but-not-blazing conditions — hazy mornings, tree-shaded streets, or partly cloudy days where a full ND32/64 would be overkill.

• 3-stop light reduction: a step up from ND4, letting you shoot with a slower shutter for smooth panning without hitting the deep cuts of the stronger filters.
• Dual-layer cinema glass: precision-aligned to cut light evenly, avoiding the color cast that cheaper filters introduce.
• Scratch-resistant, hydrophobic, anti-static coatings: resists dust and water spots — relevant when you're shooting near waterfalls, coastlines, or dusty trails.
• 37mm Filter Mount compatible: works on Moment's phone mount or any 37mm-thread camera lens, so it doubles across gear.

Shotkit's hands-on review of Moment's smartphone filter lineup found the ND filters cut light effectively "without spoiling image quality," with a rotating ring that stays put rather than loosening mid-shoot.

Best for: travelers filming in filtered daylight — shaded streets, overcast coastlines, hazy mornings. Skip it if: you're shooting in direct midday sun, where an ND32 or ND64 cuts enough light to avoid overexposure. Runs ~$30 — check the current price before buying.
