Used only once. I am selling it because I no longer use it. ・Product Name: Neewer 37MM Smartphone Lens Accessory Kit ・Set Contents: 0.45X Wide Angle Lens, Lens Clip, Graduated Color Filters (Blue, Orange, Gray), Circular Polarizing CPL Filter, Neutral Density ND2-400 Filter ・Wide Angle Lens: Can widen the field of view. Ideal for shooting larger scenes such as buildings and landscapes. ・With the adjustable ND lens filter, the photographer can adjust the required brightness by twisting it. The CPL lens filter enhances the clarity of distant objects by taking richer landscape photos, cutting haze, and increasing saturation. ・Graduated color filters are designed for shooting, especially during sunrise and sunset, to change the atmosphere of the photos. ・Durable Material: The included filters are made of HD optical glass that reduces high brightness.
