PolarPro QuartzLine Camera Filters
(Photography Blog)

PolarPro QuartzLine Camera Filters are new professional-focused filters for DSLRs, mirrorless and cinema cameras. Constructed of 99.9% pure fused quartz, the QuartzLine Filters 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. QuartzLine is available in a full collection of UV filters, polarizers, neutral density filters, and hybrid polarizing/ND filters. Filter sizes range from 37mm up to 82mm, and an array of step-up rings are offered to ensure shooters are able to use the glass on any of their lenses.
