The JJC F NC77 2 In 1 Variable ND + CPL Filter is a versatile accessory for photographers that functions both as a neutral density filter (ND) and a circular polarizing filter (CPL). This type of filter allows you to control the amount of light hitting the sensor, helping to prevent overexposure in bright environments. At the same time, the CPL filter enhances color saturation and reduces reflections, which is particularly beneficial when shooting water or glass. The variable ND filter offers the flexibility to adjust the density according to lighting conditions, providing precise control over exposure time. With a diameter of 77 mm, this filter is suitable for a variety of lenses and is easy to attach. The combination of these two filters in one product makes it a practical choice for creative photographers working in both landscape and portrait photography. The JJC F NC77 filter is therefore an essential tool for anyone looking to expand their photographic possibilities.
