SIGMA WR PROTECTOR
Water-repellent, Antistatic type

Protector is developed to protect the lens surface from dirt and dust as well as scratches. It is an ideal filter for regular use as it is completely colorless so does not affect color reproduction.

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.
