PolarPro Helix MagLock ND64/PL (6-Stop) Filter
Overview
The PolarPro Helix MagLock ND64/PL (6-Stop) filter combines a neutral density and circular polarizer in one round filter. It attaches magnetically to a compatible adapter ring rather than threading onto the lens, which makes it quick to swap between shots. The filter reduces incoming light by 6 stops, allowing wider apertures and slower shutter speeds to control exposure and enhance creative effects like motion blur. Its circular polarizer helps minimize reflections and glare from non-metallic surfaces without affecting autofocus or auto exposure. Additionally, the Helix MagLock ND64/PL (6-Stop) features a 16-layer multicoating that minimizes internal ghosting and reflections.
Features
Key Features
Neutral Density Filter
A neutral density filter cuts the light reaching the sensor without shifting color, so exposure can be set by aperture and shutter rather than by light level.
Round Screw-In Format
The filter threads directly onto the front of a lens, which suits handheld and location work where a matte box would be in the way.
6-Stop (ND64) Neutral Density
The filter reduces incoming light by 6 stops, allowing wider apertures and slower shutter speeds to control exposure and enhance creative effects like motion blur.
Circular Polarizer
Rotating the front ring varies how much reflected light is cut. A circular polarizer is used rather than a linear one so that autofocus and metering are unaffected.
16-Layer Multi-Coating
The glass carries a 16-layer multicoating that minimizes internal ghosting and reflections.
Magnetic Mount
The filter snaps onto a magnetic adapter ring instead of threading on, so filters can be swapped one-handed. The adapter ring is a separate purchase.
