The Moment Mobile Variable ND QuickLock Filter for iPhone 17 Pro/Pro Max is a sophisticated neutral density filter specifically designed for mobile photography and videography. This filter allows precise control over the amount of light hitting the sensor, ensuring evenly exposed, cinematic shots. With an adjustable range of two to seven stops of light, users can intentionally create motion blur or use wide apertures in bright environments without risking color shifts. The integrated QuickLock system enables easy and secure attachment to compatible Moment camera cases, significantly simplifying handling during filmmaking. The flat adjustment ring ensures intuitive operation, while mechanical stops prevent unwanted effects such as cross-polarization. The filter is made from lightweight, robust AeroFrame metal and features high-quality Schott B270 glass, which guarantees clear contrasts and natural skin tones. These features make the filter ideal for changing light conditions and dynamic shooting situations.
