This 10-stop, 77mm PolarPro QuartzLine ND & CPL Filter 77mm 6-Stopfrom PolarPro QuartzLine ND & CPL Filter 77mm 6-Stopis a filter that combines a solid neutral density effect with a circular polarizer effect. When in use, this filter's 64x filter factor provides a 6-stop exposure reduction. Its 1.8 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.

Simultaneously, this filter can help to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges and filters this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

This filter is constructed from quartz glass for enhanced durability. To prevent internal ghosting and reflections, 16 layers of anti-reflection coatings offer scratch protection to the filter substrate while promoting clarity and color fidelity. The coatings associated with the PolarPro 77mm ND64 QuartzLine Solid Neutral Density 1.8 and Circular Polarizer Filter also result in an improved beading effect when in contact with water or oil, allowing for more efficient cleaning.

The quartz glass is set within a brass filter ring with side knurlings that can be rotated in order to adjust the intensity of the polarization effect. Together, the brass material and knurlings prevent jamming and provide additional strength, as well as a textured grip when mounting or removing this filter from a lens.

Related Questions and Answers

Q: 1. Can I stack this filter with PolarPro 82mm Peter McKinnon Signature Edition II Variable ND 1.8 to 2.7 Filter (6 to 9-Stop) and have a great result?

A: The PolarPro 82mm ND1000 QuartzLine Solid Neutral Density 3.0 and Circular Polarizer Filter (10-Stop) has front 82mm filter threads so you coudl stack filters. It is never a good idea to stack a variable ND filter with another ND filter. This will reduce image quality.

Q: 2. Is it water resistant? Does it have water repellent coating?

A: The coatings associated with the PolarPro 82mm QuartzLine Circular Polarizer Filter also result in an improved beading effect when in contact with water or oil, allowing for more efficient cleaning.

Q: 3. Does this product fit with a lens hood?

A: A 77mm screw in lens hood or addtional filter will attach without problem. depending on lens though, attention needs to be paid to any potential vignetting that may occur with wide angle lenses. Also, some bayonet hoods may not slip over the outer ring of the filter.

Q: 4. Does the rear ring ever bind or cross-thread?

A: PolarPro 77mm QuartzLine Circular Polarizer Filter is made of Brass and well built. It will not bend / cross thread under normal circumstances.

Q: 5. Hello! Does this filter have front threads (to attach a lens cap)? Thanks!

A: Yes. 77mm front filter threads allow for use with other filters or a lens cap.

Q: 6. Where are these made? Thanks.

A: These are manufactured in China.

Q: 7. Would this filter give me rich and colorful results when doing street photography, and if so, how many stops should I go for so that I dont have to change the filter too often even if it gets dark, 3, 4 stops?... or should I go for a polarizer one? Thanks

A: Yes, it will clean up your images by saturating colors and increasing contrast. I would just go with a polarizer that would cut out about 1-2 stops.

Q: 8. Does the combo ND/PL also help w/ saturation/contrast as well or just glare reduction?

A: When using the variable circular polarizing section of the PolarPro 82mm ND64 QuartzLine Solid Neutral Density 1.8 and Circular Polarizer Filter, one can increase saturation and contrast in a photo, as well as glare reduction.

Q: 9. will it fit a sony 200-600mm lens

A: Yes, the Sony 200-600mm has a 95mm front filter thread, so this filter will fit.

Q: 10. Whether this filter can be used together with another VND Filter?

A: Yes, you can stack filters but be aware you may get vignetting when used with a wide angle lens.
