The JJC F NC55 2 In 1 Variable ND + CPL Filter is a versatile accessory for photographers, functioning both as a polarising filter and a variable neutral density filter. With a diameter of 55 millimetres, this screw filter is specifically designed for lenses that support this size. The polarising filter helps to reduce reflections and enhance colour saturation, which is particularly beneficial in landscape and nature photography. The variable ND filter allows for control over the amount of light reaching the sensor, providing greater flexibility in exposure and the use of longer shutter speeds. This is especially useful in bright lighting conditions or when capturing moving subjects to achieve creative effects. The filter is easy to handle and can be effortlessly attached to various lenses, making it a valuable addition to the gear of photography enthusiasts.
