Costa Mesa, CA—A developer of products for adventure content creators, PolarPro expanded its line of lens filters to professional photography and cinematography cameras. Known for action camera and drone filters, PolarPro debuted its professionally focused QuartzLine camera filter family. QuartzLine filters are available for DSLR, mirrorless and cinema cameras.
QuartzLine filters range from $59.99 to $249.99, depending on the size and filter style. PolarPro’s QuartzLine filter line includes circular threaded UV, polarizers and neutral density filters. Filter options include UV, CP, ND8, ND8/PL, ND16, ND16/PL, ND64, ND64/PL, ND1000 and ND100000. The line also offers hybrid single-element ND/polarizing lens filters ranging from ND4/PL to ND1000/PL. The filter sizes run from 37mm, 46mm, 67mm and 72mm to 82mm.
“As we have worked to establish PolarPro as the preferred option for drone cinematographers, we’ve also been working behind the scenes to make the QuartzLine filters into an extremely precise and consistent filter for professional photo and video creators,” said Austen Butler, cofounder of PolarPro.
“With QuartzLine, we wanted to create a rugged camera filter in line with our obsession over image quality. After testing 29 different materials, we landed on a fused quartz glass element, with hyper neutral coatings to reduce reflectivity, increase scratch resistance, and most importantly, delivery a consistently neutral color profile.”
QuartzLine camera filters combine PolarPro’s Death Valley-tested coatings with premium materials. Constructed of 99.9% pure fused quartz, the filters are designed to “set a new bar for light transmission and purity as the rare, fused quartz element delivers an extremely low refractive index compared to traditional filters,” Butler added.
The fused quartz glass helps to ensure the filters have an extremely low refractive index of 1.46. As a result, the filters are engineered to exhibit increased stability and temperature resistance (from -50ºF to 130ºF), so content creators can bring the true-life colors to their product from the most extreme locations.
Moreover, the new optical coating method was added to reduce surface reflectivity to less than one percent. It also increases surface hardness—while maintaining a neutral color profile. The filters’ light transmission is said to be “perfectly neutral from the UV spectrum all the way across the IR spectrum, which gives photographers and cinematographers the confidence to stretch the boundaries of their creative vision while ensuring color and image accuracy.”
Furthermore, PolarPro is leveraging its new advanced coating technologies to eliminate any color cast or color shifting inconsistency throughout the spectrum. It also reduces flare and ghosting. And since the single-element QuartzLine filters are available in an array of ND and ND/PL filters, photographers and cinematographers do not have to stack glass to achieve a desired effect. They also permit wide-angle shots without the fear of vignetting, Butler noted.
QuartzLine Filters’ Additional Features
In addition, each of PolarPro’s QuartzLine filters feature the following:
- Neutral Density Coating. Applied to reduce the desired light transmission without incurring color shifts, PolarPro ND coatings have been tested in demanding conditions. These span the workshop test bench to sunblasted skies.
- Antireflective Coating. Reducing the reflectivity of the lens filter eliminates hot spots in the frame. PolarPro’s coating technology was developed to allow the 3.45% native reflectivity of the fused quartz to be reduced to a negligible 0.455%.
- Anti-Scratch Coating. To protect the coatings and base glass as well as harden the filters surface, PolarPro added anti-scratch coating.
- Hydrophobic Coating. Increasing surface hardness while making for easier cleaning and water resistance, PolarPro’s hydroscopic coating provides the external layer on QuartzLine filters.
Furthermore, the four-part frame that houses each QuartzLine filter was overengineered to ensure it threads align onto each lens. Also, PolarPro exchanged traditional aluminum frames in favor of more durable, yet lightweight, brass frames. QuartzLine filters showcase the brass exterior portion of the frame. However, the interior is coated in a matte back to prevent unwanted reflections.
In addition to accommodating an array of lens sizes, the QuartzLine series also offers optional step-up rings. The rings allow the filters to be used with most professional lenses. Step-up rings are available in the following configurations: step 52mm, 55mm and 58mm lens to 67mm filter; step 62mm, 67mm and 72mm to a 77mm filter; and step 62mm, 67mm, 72mm and 77mm lens to an 82mm filter.
Also, all QuartzLine Filters can be paired with PolarPro’s rugged Kanga camera filter case ($39.99). The case has a magnetic opening for quick filter access, a microfiber interior lining and a pull-tab system for streamlined filter selection. polarpro.com
