The Moment Variable ND QuickLock Filter for iPhone 17 Pro Max is a precision mobile neutral density filter designed for controlled exposure in bright environments. It allows smooth adjustment from 2 to 7 stops of light reduction, enabling consistent motion blur and balanced exposure for cinematic smartphone video and high-quality still photography.

Designed for the Moment QuickLock ecosystem, the filter attaches directly to compatible iPhone 17 Pro Max camera cases via a secure press-and-lock mechanism. Its multi-coated optical glass helps maintain accurate color reproduction while reducing overexposure in daylight shooting conditions.
