Basic protective filter

This filter prevents dust, dirt, and scratches from damaging the lens surface. Completely colorless and transparent, it does not affect color reproduction, making it ideal for use as a permanent lens attachment.

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.
