The PolarPro Helix MagLock ND8 (3-Stop) filter is a round neutral density 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 3 stops, allowing a wider aperture or a slower shutter in bright conditions. Additionally, the Helix MagLock ND8 (3-Stop) features a 16-layer multicoating that minimizes internal ghosting and reflections.
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.
3-Stop (ND8) Neutral Density
The filter reduces incoming light by 3 stops, allowing a wider aperture or a slower shutter in bright conditions.
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.
