Product Description
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.
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.
