Sigma 82mm WR Ceramic Protector filter

Sigma 82mm WR Ceramic Protector filter

Sigma Ceramic Protection is designed to protect the front element of your lens from dirt, dust, scratches and impacts. The protective filter is completely colorless, so it does not affect the color reproduction of the image in any way.

The difference between ceramic glass and normal reinforced glass is that ceramic glass is reinforced throughout, while reinforced glass is only reinforced on the surface. Because the glass is reinforced throughout, the thickness of the filter glass has been reduced by 50% and the weight has also dropped by 30% (compared to previous Sigma Protection filters).

WR or Water Repellent
The coating on Sigma's WR filters is water and oil repellent, which makes cleaning the filter easier.

Antistatic
Thanks to the filter's antistatic coating, small dust particles can be blown away more easily.
