About Sigma PTC-21 WR Ceramic Protector Filter

Sigma Lens Filters

Sigma launches the renewal of its filter series for interchangeable lenses. The entire lineup has been completely redesigned to achieve further performance improvements.

Sigma WR Ceramic Protector Filter

A ceramic protector offering exceptional impact resistance. Featuring "Clear Glass Ceramics", a high strength material also used in aerospace and other advanced industries. Combining hardness superior to conventional chemically strengthened glass with flexibility greater than sapphire crystal, this flagship protector possesses the ideal properties for lens protection.

Sigma WR Ceramic Protector

WR coating

The WR coating, which combines superior water repellency and oil resistance with antistatic properties, repels water droplets, fingerprints, and fine dust, making any smudges easy to wipe away.



Exposure

Using this filter does not affect exposure.


Note: Should the filter break from a drop or strong impact, handle with care to avoid glass fragments, as they can cause injury.
