VND (2-7 Stop) QuickLock Filter, iPhone 15 Pro/Pro Max

Moment VND QuickLock Filter — a cinema-camera look for client video, shot entirely on iPhone

The gist: If you're offering video production as part of a freelance service, this variable ND filter lets you hit the smooth, cinematic 24fps motion clients associate with professional cameras — on an iPhone, in bright outdoor conditions where that shot is normally impossible.

• 2-7 stop range on one dial: adjusts from a little darker to much darker, so you're not carrying multiple fixed-strength filters between locations or lighting setups on a shoot.
• Cinema-grade glass: Schott B270 Pro Cinema Glass avoids the color shift and uneven darkening that cheaper variable ND filters are known for — a real factor in deliverables you're billing a client for.
• Fast on-set attachment: the QuickLock press-and-lock system requires no threads or tools and covers all three iPhone lenses without repositioning between them, useful when you're working on the clock.
• Mounting requirement: it attaches to a Moment Case (sold separately), not directly to a bare phone, so factor that into your kit cost.

9to5Mac's hands-on review found it took "literally two seconds" to attach and confirmed reliable 24fps shooting "in extreme conditions" with direct sunlight, with the reviewer saying they "can't recommend it highly enough" and are replacing their bulkier cage-based ND setup with it.

Best for: freelance videographers offering iPhone-based production who need a fast, professional-looking exposure solution outdoors. Skip it if: you don't already have (or plan to buy) a compatible Moment Case — it won't mount without one. Runs ~$50 — check the current price before buying.
