Sigma’s new Water Repellent Ceramic Protector

Sigma unveiled WR (Water Repellant) Ceramic Protector filters. These protective lens filters are claimed by Sigma to be “world’s first highly shock-resistant and scratch-resistant clear glass ceramic protective filter”. The core specs are:

  • 10x the strength of a conventional protective filter and 3x the strength of a chemically hardened glass filter
  • Optically clear ceramic glass offers extremely high transmittance
  • Water-repellent (WR) coating reflects only 0.24 percent of visible light, thereby minimizing flare and ghosting

Sigma states that their WR Ceramic Protector filters allow for 99.76% light transmission. 67mm, 72mm, 77mm, 82mm, 86mm, 95mm and 105mm sizes will be available. Pricing and availability are not known for the time being.
