M-Series | 37mm ND Filter, ND 64

Moment M-Series 37mm ND 64 Filter — the heavy-duty option for harsh-light client shoots

The gist: A 6-stop ND filter — the strongest single-density option in Moment's 37mm line — for freelance videographers who occasionally land shoots in brutal midday sun: rooftop events, poolside brand shoots, or exterior real estate under a cloudless sky.

• 6-stop light reduction: the deepest cut in Moment's lineup, keeping footage exposed properly instead of choppy or blown out under direct overhead sun.
• Dual-layer cinema glass: aligned to cut light evenly, minimizing color-correction work before client delivery.
• Scratch-resistant, hydrophobic, anti-reflective coatings: holds up to repeated packing between job sites.
• 37mm Filter Mount compatible: works across a phone rig and any 37mm-thread camera in a freelance kit.

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 built to hold steady during a shoot.

Best for: freelancers who occasionally shoot outdoor client work in the harshest midday sun. Skip it if: most of your shoots are indoors or in moderate daylight — this is a specialty, not everyday, filter. Runs ~$30 — check the current price before buying.
