M-Series | 37mm ND Filter, ND 8

Moment M-Series 37mm ND 8 Filter — a middle-ground exposure tool for outdoor client shoots

The gist: A 3-stop ND filter that gives freelance videographers finer exposure control for shoots in partly bright conditions — outdoor interviews under a tree line, shaded office courtyards, hazy-sky product demos.

• 3-stop light reduction: enough to slow the shutter for smoother motion without the heavy darkening of a stronger filter, useful when lighting on a job site varies through the day.
• Dual-layer cinema glass: cuts light evenly, reducing the color-correction work needed in post — a real time savings on billable freelance hours.
• Scratch-resistant, hydrophobic, anti-static coatings: durable enough to travel between client sites in a gear bag without babying it.
• 37mm Filter Mount compatible: works across a phone rig and any 37mm-thread camera, useful if your freelance kit mixes gear.

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 not to loosen during a shoot.

Best for: freelance content creators shooting client video in partly bright, filtered daylight. Skip it if: you mostly shoot in direct sun (an ND32 or ND64 cuts more) or entirely indoors under artificial light. Runs ~$30 — check the current price before buying.
