The Sigma 105mm WR UV Protector Filter prevents the bluish tone in bright sunny weather by absorbing ultraviolet rays – particularly in film cameras. Completely colourless, and comes standard with Sigma’s WR coating.
The Sigma 105mm WR UV Filter is a general use, clear filter that helps to absorb ultraviolet light and reduce the bluish cast of daylight. This filter is especially useful when photographing at high altitudes or around bodies of water. No additional coloration or contrast is provided, allowing you to pair this filter with others.
A UV filter is also useful as a general protective filter to leave on a lens at all times. This filter helps to reduce dust and moisture from reaching your front lens element and provides additional protection in case of drops or situations where scratching could occur.
This Sigma WR UV Filter is coated to repel water drops and resist smudging from fingerprints. It is also treated to exhibit antistatic properties to prevent microscopic dust from clinging to the front surface. This helps to ensure sharp images.
The Sigma Professional Series represents the finest quality of filters available for your photographic lens, enhancing your overall experience with your camera and photography.
The Sigma WR (water repellent) Filters feature new anti-reflective coatings and a glass mounting system that contribute to exceptionally high-quality imaging designed for digital SLR photography.
When pitted against the standard coating offered by other brands, the benefits of Sigma’s ultra-low reflection multicoated optics are crystal clear.
Digital camera CCD or CMOS sensors are highly reflective objects and therefore susceptible to reflections. These reflections could spoil your photographs. Sigma Professional Filters have an ultra-low reflection multi-coating that dramatically reduces potential of sensor reflections and flare.
Key Optimizing Features
Black-Rimmed Glass Reduces light reflection off filter edge.
Premium Hard Anodized Black Frame Finish Aesthetically functional design that blends well with the fit and finish of professional lenses.
Low Profile Filter Rim Prevents vignetting with wide-angle focal length lenses. Designed to accept lens caps.

Applicable to all but the Standard Protector Filter, the anti-static coating helps prevent static electricity from attracting dust and other particles, which can easily be blown off the filter if they do adhere.
Water & Oil Repellent Coating
Conventional Protective Filter
Applicable to all but the Standard Protector Filter, the surface of the filter is specially coated to offer excellent water and oil-repellent performance. Watch water and oil ricochet while dust that does adhere blows away and fingerprints removes with one wipe.
Wide Angle Capability
Low-profile filter rim prevents vignetting with wide-angle focal length lenses.
