PolarPro QuartzLine ND8 (3 Stop) Filter 77mm

PolarPro QuartzLine ND8 (3 Stop) Filter 77mm – 99.9% Fused Quartz for Clear, True-to-Life Images

The PolarPro QuartzLine ND8 (3 Stop) Filter in 77mm delivers precise neutral density control while preserving clarity and accurate color rendition. Designed for filmmakers and photographers, this filter uses 99.9% pure fused quartz glass to maintain sharpness and true-to-life color, whether you are balancing bright outdoor light or creating long-exposure effects.

Designed for demanding shooting conditions

Filmmakers and photographers use the QuartzLine ND8 to manage exposure without compromising image quality. You can dial in three stops of light reduction to achieve motion blur, control depth of field, or keep highlights in check under bright skies. Additionally, the filter’s materials and construction make it suitable for field work and professional shoots where reliability matters.

Optical construction and coatings

• Pure fused quartz glass: The filter glass is made from 99.9% pure fused quartz to ensure high clarity and accurate color reproduction.
• Multi-coated surfaces: PolarPro’s advanced multi-coating reduces reflections, flares, and ghosting, which helps you preserve contrast in harsh lighting.
• Neutral density control: This specific product is an ND8 (3 Stop) filter, and QuartzLine is also available across a range of strengths from ND8 to ND100K for different exposure needs.

Durable mechanical design for field use

The QuartzLine ND8 combines premium optical materials with a robust frame and protective coatings. The construction supports frequent use and quick changes on set.

• Ultra-durable brass frame: The frame is made of aerospace-grade brass and features a knurled design to make attachment and removal easy and secure.
• Scratch-resistant coating: A protective coating helps resist everyday wear, keeping the optical surface usable for longer.
• Hydrophobic and oleophobic treatments: Water and oil repellent coatings make the filter easier to clean and reduce fingerprints, which is useful when shooting in rugged or wet environments.
• Protective case included: The filter ships with a custom protective case to keep it safe in transit and storage.

FAQ

Question: Will this filter fit my lens?

Answer: The PolarPro QuartzLine ND8 shown here has a 77mm thread size. If your lens accepts 77mm filters, it will mount directly. Otherwise, you can use a step-up or step-down ring that matches your lens thread to 77mm.

Question: How does the fused quartz glass affect image quality?

Answer: Fused quartz provides high clarity and consistent color accuracy. In practice, this means less risk of unwanted color shifts and better sharpness when you reduce exposure with an ND filter.

Question: Is the filter suitable for outdoor or rugged use?

Answer: Yes. The aerospace-grade brass frame, scratch-resistant coating, and hydrophobic/oleophobic surface treatments make the filter durable and easier to keep clean in challenging environments.

Question: Can I use this filter for long exposures and filmmaking?

Answer: Absolutely. The ND8 (3 Stop) density helps you control exposure to create motion blur, slow shutter effects, or better aperture control for cinematic depth of field. For heavier light reduction, PolarPro offers the QuartzLine series in additional strengths up to ND100K.

Question: What comes with the filter to protect it during travel?

Answer: The package includes a custom protective case and a microfiber cleaning cloth to help you store and maintain the filter while traveling or on set.
