The Peter McKinnon Helix Variable ND Filter (6–9 Stop) is designed for controlling exposure in extremely bright conditions. It enables wide-aperture shooting and slower shutter speeds, supporting cinematic motion blur and shallow depth of field in both photography and video production.

Engineered for the Helix MagLock™ magnetic system, it features a 6–9 stop range (1.8–2.7 optical density), multi-coated glass, brass construction, and a haptic feedback control ring. Ideal for filmmakers and outdoor creators requiring secure mounting and rapid filter changes.
