The PolarPro 77mm Chroma VND/PL 6-9 Stop Black Mist filter combines neutral density, diffusion and a circular polarizer in one round 77mm filter. It attaches to a lens's 77mm front thread and can be stacked with other filters via its own 77mm thread. Density is adjustable across 6-9 Stop, a range intended for bright sun and long exposure rather than general use. Diffusion is rated at 1/4 strength, a moderate grade, the one most often reached for on faces. Its circular polarizer helps minimize reflections and glare from non-metallic surfaces without affecting autofocus or auto exposure. Additionally, the 77mm Chroma VND/PL 6-9 Stop Black Mist 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.
77mm Filter Thread
The filter threads onto a 77mm front thread. A lens with a different thread needs a step ring.
77mm Front Thread
The front of the filter carries its own 77mm thread, so a second filter or a hood can be mounted in front of it.
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.
1/4 Diffusion
Diffusion is rated at 1/4 strength, a moderate grade, the one most often reached for on faces.
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.
