The Caruba UV + CPL + Variable ND2 400 Set is a versatile lens filter set with a diameter of 46 mm, designed for photographers and videographers. This set includes a UV filter that blocks unwanted UV rays while enhancing the clarity and sharpness of images. The CPL filter (Circular Polarizing Filter) reduces reflections and improves color saturation, which is particularly beneficial for shots of water or in nature. The variable ND filter (Neutral Density Filter) allows for flexible adjustment of the amount of light hitting the sensor, offering a density range from ND2 to ND400. This is especially useful for long exposures and controlling exposure times in bright lighting conditions. The screw filters are easy to mount and provide high optical quality to ensure image integrity. This set is a valuable addition to any photo or video equipment and supports creative expression in various lighting conditions.
