Sigma 58mm WR UV Protection Filter PUV-21 

This protective filter cuts ultraviolet light to prevent the bluish tint often seen in sunny conditions, while offering excellent water repellency and oil resistance. Combining clear rendering with ease of maintenance, it is the perfect choice for use as a permanent lens attachment.

Completely new design

Internal reflections are suppressed through a redesigned frame surface treatment, minimising any impact on image quality. Furthermore, an optimised 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.
