Neewer Clip On filter set for FL-37 37mm ND2-ND400 phone

Want to take even better photos with your smartphone? Meet the Neewer FL-337 filter. With the variable ND filter (ND2-ND400) you will gain the ability to fine-tune your exposure. The filter reduces the amount of light entering the lens, allowing you to avoid overexposure in bright conditions, improve color contrast and create a motion blur effect. This is especially useful when photographing dynamic scenes, such as flowing water, traffic, the ocean or changing cloud formations.
