Sigma WR Protector filter 77mm

The Sigma WR Protector filter is a water-repellent protection filter for your lens. With a diameter of 77mm, it fits any lens with a matching thread size. The filter has no impact on image quality, but does keep dust, moisture and other elements at bay. It also eliminates the risk of damage to your lens's precious glass elements. The filter features multiple coatings to combat ghosting. An anti-static coating prevents the filter from building up a static charge, which means dust is not attracted to the surface. The water-repellent (WR; Water Repellent) layer also ensures that both water and oil can be easily wiped away from the filter.
