PolarPro QuartzLine ND16 (4 Stop) Filter 77mm

PolarPro QuartzLine ND16 (4 Stop) Filter 77mm – Precision 4-Stop Neutral Density Control

This PolarPro QuartzLine ND16 (4 Stop) Filter in 77mm thread size gives filmmakers and photographers precise neutral density control. It reduces light by four stops to help you manage exposure in bright conditions and achieve motion blur or balanced exposure without changing aperture or shutter speed. The filter forms part of the QuartzLine series, which focuses on optical clarity and field-ready durability.

Designed for filmmakers and photographers

PolarPro designed the QuartzLine ND filters specifically for creators who require high optical performance and robust construction. Consequently, this ND16 filter suits a range of shooting scenarios, from bright outdoor filming to controlled long-exposure photography. It fits lenses with a 77mm thread size.

Optical quality and materials

The filter uses 99.9% pure fused quartz glass, which delivers high clarity and accurate color reproduction. Moreover, PolarPro applies advanced multi-coating technology to reduce reflections, flares, and ghosting. As a result, you maintain image sharpness and true-to-life color when you add ND control to your setup.

Durability and construction

PolarPro builds the QuartzLine ND filters for demanding environments. For instance, the frame is made from aerospace-grade brass, giving the filter a durable, premium feel and reliable longevity. Additionally, the frame features a knurled design for easier attachment and removal in the field.

Protective and practical surface treatments

The filter includes several protective coatings to simplify use and maintenance. First, a scratch-resistant coating helps protect the optical surface from everyday wear. Second, hydrophobic and oleophobic treatments repel water, oil, and fingerprints, making the filter easier to clean and more resilient in rugged conditions. Lastly, PolarPro includes a custom protective case for transport and storage.

Available strengths and control

PolarPro offers QuartzLine ND filters across a broad range of densities. While this listing is for the ND16 (4 Stop) version, the QuartzLine family provides options from ND8 up to ND100K, allowing precise exposure control across different creative and technical needs.

FAQ

Question: Is this filter suitable for both filmmaking and photography?
Answer: Yes. PolarPro designed the QuartzLine ND16 for filmmakers and photographers who need precise exposure control and optical clarity in bright or demanding conditions.

Question: Will this fit my lens?
Answer: The listed thread size is 77mm. Therefore, the filter fits lenses with a 77mm front thread. If your lens uses a different thread, use an appropriate step-up or step-down ring to adapt.

Question: How does the filter handle cleaning and harsh conditions?
Answer: The filter has scratch-resistant and hydrophobic/oleophobic coatings, which repel water and oil and reduce fingerprints. Additionally, PolarPro includes a microfiber cloth and a protective case for safer storage and easier maintenance.

Question: What are the practical uses of a 4-stop ND like the ND16?
Answer: An ND16 reduces exposure by four stops, which helps control bright daylight exposure, allow slower shutter speeds for motion blur, or maintain wider apertures in bright environments without overexposure.
