This 10-stop, 67mm QuartzLine Solid ND and Circular Polarizer Filter from PolarPro is a filter that combines a solid neutral density effect with a circular polarizer effect. When in use, this filter's 1000x filter factor provides a 10-stop exposure reduction. Its 3.0 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 67mm ND1000 QuartzLine Solid Neutral Density 3.0 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 this filter be used with Sony 24-70 GMII with lenshood on?

A: Yes, this will work with the Sony 24-70mm GMII lens hood. The hood features a "window" to access the polarizing ring.

Q: 2. How does this compare to the ND1000 without the polarizer? Does adding the polarizer feature have any negative impact on the quality of the ND aspect of it?

A: Having the added polarizer allows you to reduce reflection or glare in addition to reducing the exposure overall.

Q: 3. Where are these made? Thanks.

A: These are manufactured in China.

Q: 4. Curious if this ND/PL stacked with a Tiffen Black ProMist on a 24mm lens will cause vinette problems (@f/1.4 thru f/4)? I'm thinking it likely will and might then go for non PL version as it looks slightly thinner? Cheers if anyone's already test this out?

A: If you use this on a full-frame camera, you would be likely to have some vignetting. On a crop-sensor camera, it would be less likely.

Q: 5. Can you stack PolarPro ND filters?

A: The PolarPro 82mm ND1000 QuartzLine Solid Neutral Density 3.0 and Circular Polarizer Filter (10-Stop) have front filter threads, so you could stack them with other filters.

Q: 6. 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: 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. Lens cap fits?

A: The PolarPro 82mm QuartzLine Circular Polarizer Filter has a front 82mm filter thread. So, it can use many front lens caps. These are some of them: https://bhpho.to/3KX6QmZ.

Q: 9. would this work with the tilta mini matte box if I added an extension ring in there?

A: Yes, It comes with an 82mm adapter ring.

Q: 10. 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.
