M-Series | 37mm ND Filter, ND 64

Moment M-Series 37mm ND 64 Filter — the strongest single-filter option for peak midday sun

The gist: A 6-stop ND filter — the strongest single-density option in Moment's 37mm line — built for filming in the harshest light travel throws at you: equatorial midday sun, glacier and snowfield glare, or open water reflections.

• 6-stop light reduction: the heaviest cut Moment offers in a single filter, letting you shoot a natural, slower shutter even when the sun is directly overhead.
• Dual-layer cinema glass: aligned to cut light evenly across the frame, avoiding the color shift or vignette cheaper heavy-ND filters can introduce.
• Scratch-resistant, hydrophobic, anti-reflective coatings: holds up against salt spray, dust, and the wear of daily travel filming.
• 37mm Filter Mount compatible: works on Moment's phone mount and any 37mm-thread camera lens.

Shotkit's hands-on review of Moment's smartphone filter lineup found the ND filters cut light "without spoiling image quality," with a rotating ring designed to stay put through handheld shooting.

Best for: travelers filming in the brightest possible conditions — snow, glaciers, open water, equatorial midday sun. Skip it if: you're shooting in anything less than harsh direct light — this filter will make footage too dark. Runs ~$30 — check the current price before buying.
