SIGMA WR CIRCULAR PL FILTER
PL Water-repellent, Antistatic type
Circular PL filter removes the reflection of water surface and glass windows, and increases the contrast in landscape photography.
*WR：Water Repellent
Water-repellent (WR) coating
The WR coating reflects only 0.24 percent of visible light, thereby minimizing flare and ghosting. Its ability to repel both water and oil is also excellent: water drops bounce right off, and fingerprints are easily removed with a quick wipe. This coating also offers high lubricating ability, giving it more than ten times the scratch-preventing capability of SIGMA's current Super Multi-Layer Coating. The coating's antistatic function helps prevent static electricity from attracting dust and other particles, which can easily be blown off the filter when they do adhere.
