30.5Mm Circular Polarising Filter (30.5Mm Cpl) Hoya
Hoya 30.5mm Circular Polarizer Filter is a lightweight and durable filter that can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. This filter eliminates ultraviolet rays to remove haze from outdoor shots as well as polarizing the light to remove reflections, and increase color saturation, without affecting the overall color balance. The effect can be seen through the viewfinder and changed by rotating the filter. Its filter factor varies according to how the filter is rotated and its orientation to the sun.
