The PolarPro 67mm QuartzLine ND16 (4-Stop) filter is a round 67mm neutral density filter. It attaches to a lens's 67mm front thread and can be stacked with other filters via its own 67mm thread. The filter reduces incoming light by 4 stops, allowing wider apertures and slower shutter speeds to control exposure and hold a cinematic shutter angle in daylight. Additionally, the 67mm QuartzLine ND16 (4-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.
67mm Filter Thread
The filter threads onto a 67mm front thread. A lens with a different thread needs a step ring.
67mm Front Thread
The front of the filter carries its own 67mm thread, so a second filter or a hood can be mounted in front of it.
4-Stop (ND16) Neutral Density
The filter reduces incoming light by 4 stops, allowing wider apertures and slower shutter speeds to control exposure and hold a cinematic shutter angle in daylight.
16-Layer Multi-Coating
The glass carries a 16-layer multicoating that minimizes internal ghosting and reflections.
