The new Sigma Water Repellent (WR) Ceramic Protector is a shock- and scratch-resistant Clear Glass Ceramic filter that is 10 times stronger and a conventional protective filter and three times the strength of a chemically strengthened filter.
It also features a WR coating that repels water, dust and oil, allowing fingerprints to be easily removed.
Sigma’s Water Repellent (WR) Ceramic Protector is available in thread sizes ranging from 67mm to 105mm. No word yet on price or availability but we should know more soon. For a frame of reference, Sigma’s current, non-ceramic WR Protector filters range from about $50 to $175 depending on the diameter.
