The PolarPro 82mm QuartzLine ND100K (16.6-Stop) filter is a round 82mm neutral density filter. It attaches to a lens's 82mm front thread and can be stacked with other filters via its own 82mm thread. The filter reduces incoming light by 16.6 stops, a density intended for solar work rather than general shooting. Additionally, the 82mm QuartzLine ND100K (16.6-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.
82mm Filter Thread
The filter threads onto an 82mm front thread. A lens with a different thread needs a step ring.
82mm Front Thread
The front of the filter carries its own 82mm thread, so a second filter or a hood can be mounted in front of it.
16.6-Stop (ND100K) Neutral Density
The filter reduces incoming light by 16.6 stops, a density intended for solar work rather than general shooting.
16-Layer Multi-Coating
The glass carries a 16-layer multicoating that minimizes internal ghosting and reflections.
