The Moment Variable ND QuickLock Filter for iPhone 17 Pro is a smartphone-mounted variable neutral density filter designed for controlled exposure in bright lighting conditions. It enables adjustable light reduction from 2 to 7 stops, allowing users to maintain cinematic motion blur and balanced exposure while shooting video or stills in daylight environments.

Built for the Moment QuickLock ecosystem, the filter attaches directly to compatible iPhone 17 Pro camera cases using a press-and-lock mechanism. It uses multicoated optical glass designed to maintain a neutral color profile with minimal color shift, supporting consistent imaging for mobile filmmaking, vlogging, and outdoor content production.
