M-Series | 37mm ND Filter, ND 4

Moment M-Series 37mm ND 4 Filter — controlled exposure for freelance video work

The gist: A 2-stop ND filter that gives freelance videographers and content-creating remote workers fine control over exposure during softer-light shoots — interviews near a window, overcast outdoor B-roll, early-morning client shoots.

• 2-stop light reduction: the mildest ND option in Moment's range, useful when you need just a small amount of exposure control rather than a heavy cut.
• Dual-layer cinema glass: cuts light evenly without introducing color shifts that would need correcting in post — a time-saver on a paid gig.
• Scratch-resistant, hydrophobic coating: holds up to being packed and unpacked between client locations.
• Fits Moment's 37mm Filter Mount: usable on a phone rig or any camera with a 37mm filter thread, useful for a mixed phone-and-camera 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 designed not to unscrew mid-shoot — a practical detail for anyone shooting client work under time pressure.

Best for: freelancers or side-hustling remote workers filming client video in soft or overcast light. Skip it if: your shoots are mostly in bright midday sun, where a stronger ND32 or ND64 is more useful. Runs ~$15 — check the current price before buying.
