PolarPro QuartzLine 82mm, ND16 Polarizer Filter

1.2 neutral density filter effect darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required Providing a 16x filter factor with a 4-stop exposure reduction, this filter allows you to control depth of field and convey movement more easily Polarizing filter effect arranges and filters directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface Clears up haze in distant landscapes and provides more saturated, vivid colors Strongest polarization effect when used at a 90° angle from the sun Circular polarizer effect is ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features Multi-coated to prevent internal ghosting and reflections while promoting clarity as well as color fidelity Brass filter ring helps to prevent jamming and provides additional strength Filter ring can be rotated to adjust the intensity of the polarization effect 82mm front filter threads allow for use with other filters Side knurlings provide a textured grip when mounting or removing from a lens Plastic filter case and padded pouch for storage and transport Microfiber cloth for cleaning and maintenance
