M-Series | 37mm ND Filter, ND 16

Moment M-Series 37mm ND 16 Filter — the all-rounder for typical daytime travel light

The gist: A 4-stop ND filter that sits in the middle of Moment's range — a solid default for typical daylight travel filming, from partly sunny plazas to bright but not blinding beach mornings.

• 4-stop light reduction: strong enough to tame most daytime brightness while still leaving room to shoot handheld without an overly dark image.
• Dual-layer cinema glass: cuts light evenly across the frame for a natural rolloff instead of a harsh vignette.
• Scratch-resistant, hydrophobic, anti-reflective coatings: holds up to being packed daily for weeks of travel filming.
• 37mm Filter Mount compatible: works on Moment's phone mount or a 37mm-thread camera lens.

Shotkit's hands-on review of Moment's smartphone filter lineup praised the ND filters for cutting light "without spoiling image quality" and noted the rotating ring is designed to stay secure during a shoot.

Best for: travelers who want one general-purpose ND for most typical daytime light without carrying the whole 5-strength set. Skip it if: you're shooting mostly at golden hour (go lighter, ND4/ND8) or in peak midday sun (go stronger, ND32/ND64). Runs ~$30 — check the current price before buying.
