PolarPro QuartzLine 67mm, ND64 Polarizer Filter

1.8 neutral density filter effect darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required Providing a 64x filter factor with a 6-stop exposure reduction, this filter allows you to control the depth of field and convey movement more easily Polarising filter effect arranges and filters directionally polarised 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 polarised due to reflection from a non-metallic surface Clears up haze in distant landscapes and provides more saturated, vivid colours Strongest polarisation effect when used at a 90° angle from the sun The circular polariser effect is ideal for use with digital cameras and autofocus lenses where a linear polariser will often disrupt auto exposure and focus features Constructed from quartz glass for enhanced durability Multi-coated to prevent internal ghosting and reflections while promoting clarity as well as colour fidelity Brass filter ring helps to prevent jamming and provides additional strength The filter ring can be rotated to adjust the intensity of the polarisation effect 67mm 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
