High-strength ceramic protective filter

This protector filter features "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.

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.

Completely new design

Internal reflections are suppressed through a redesigned frame surface treatment, minimizing any impact on image quality. Furthermore, an optimized design has allowed for a thinner profile in the large-diameter 95mm and 105mm sizes.

Verified compatibility with all Sigma lenses

Compatibility with all Sigma lenses has been fully verified, allowing for shooting without the worry of vignetting, even when using ultra-wide-angle lenses. Despite the slim design, it ensures secure lens cap attachment for peace of mind.
