The Crystal Optics 43mm Filter Kit bundles three essential must have filters that no photographer should be without including a UV (ultraviolet), PL (polarizing), and FLD (fluorescent) filter. The UV filter not only removes UV light, it also protects your lens from moisture, scratches, and damage. The PL filter provides color and contrast enhancement and corrects reflected light that often shows up on images as a whitish glare. It also removes glare from non-metallic surfaces such as windows and water. Finally, the FLD filter provides color correction when shooting under fluorescent lighting and removes the greenish tint from images. This results in images that have pleasing skin tones and true-to-life color renditions. This 3-piece filter kit includes a compact protective carrying case for transporting and storing your set of lens filters when not in use. Key Features: Multi-Coated Super High Resolution Includes UV, PL, Fluorescent Carrying Case
