The Protector protects the lens surface from dirt and dust, as well as scratches. It is an ideal filter for regular use as it is completely colorless so it does not affect color reproduction.
The Sigma Professional Series represents the finest quality of filters available for your photographic lens, enhancing your overall experience with your camera and 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.
Low-profile filter rim prevents vignetting with wide-angle focal length lenses.
Made of a special acrylic that is both stronger and more flexible, this storage case is designed to outlast others of its kind. The outer acrylic case is molded for optimal integration with the inner elastomer holder, creating a filter holder designed to last many years with minimal deterioration. It comes equipped with a closure system designed to prevent accidental open or closure during normal use.
SIGMA’s lens filters are made completely in Japan, including all individual processes used in its manufacture.
