52mm Bullet Optics Protective Multi Coated Anti-Glare Circular Polarizer Filter for 55-200mm f/4-5.6G ED AF-S DX Zoom-Nikkor Lens

This Bullet Optics CPL Filter removes the reflections of light from metallic surfaces from your photos. The light and rays from the sun get polarized and do not negatively affect the outcome of your photos. It can also remove unwanted reflections from non-metallic surfaces such as water or glass. You can change the effect of the filter by rotating the filter until desired effect is achieved.
