The PolarPro Helix MagLock VND 6-9 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. Density is adjustable across 6-9 Stop, a range intended for bright sun and long exposure rather than general use. Additionally, the Helix MagLock VND 6-9 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.
6-9 Stop Variable Neutral Density
Density is adjustable across 6-9 Stop, a range intended for bright sun and long exposure rather than general use.
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.
