This 4-stop, 77mm QuartzLine Solid ND Filter from PolarPro is an ND filter with a 16x filter factor that provides a 4-stop exposure reduction. Its 1.2 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time or increasing your aperture, you can control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

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 this 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. 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 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: 2. Does this work with a Canon R5 24-105 lens (77mm) - and if so, can I screw it into the UV-Haze filer that I keep on this lens for protection?

A: Yes, the PolarPro 77mm QuartzLine Circular Polarizer Filter will work with a Canon 24-105mm lens; any 77mm filter will adapt to a Canon 24-105mm lens. We highly suggest using slim-profile filters to avoid vignetting issues.

Q: 3. Is it easy to see the effect of the polarizer and set it properly since the filter is so dark?

A: It is not as easy as when you have the ND and polarizer filters separate, but the best option is to increase the ISO a lot to focus and also to set the polarization and then turn the ISO down to take the picture.

Q: 4. 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: 5. Will this filter fit with the Sony 70-200 GM Hood?

A: Yes, you will be able to attach a filter with the lens hood on.

Q: 6. 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: 7. Is this a variable filter? Can I move trough to 1 to 10 steps?

A: PolarPro 82mm ND1000 QuartzLine Solid Neutral Density 3.0 and Circular Polarizer Filter (10-Stop) is not a variable filter. It is always at 10 stop light reduction.

Q: 8. will PolarPro 82mm ND1000 QuartzLine Circular Polarizer Filter (10-Stop) cause vignetting at 15mm of Canon RF 15-35 F/2.8 lens?

A: The PolarPro 82mm ND1000 QuartzLine Solid Neutral Density 3.0 and Circular Polarizer Filter (10-Stop) will not vignette at 15mm on the Canon RF 15-35mm f/2.8 L IS USM Lens (Canon RF).

Q: 9. What is the filter thickness? Not stated in the specs. Thx

A: Screw-on filters like the Polar Pro ND64 QuartzLine do not traditionally specify filter thickness. We measured ours at the store and without the filter threads, the filter measures 6.21mm thick.

Q: 10. 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.
