Would you like to take even better photos with your smartphone? Get to know the Neewer FL-37 filter. The variable ND filter (ND2-ND400) allows you to fine-tune your exposure. The filter reduces the amount of light entering the lens so you can avoid overexposure in bright conditions, improve colour contrast and create a motion blur effect. This is particularly useful when photographing dynamic scenes such as flowing water, traffic, the ocean or changing cloud formations. The Neewer FL-37 filter is designed for easy mounting on various devices. The mounting clip allows quick and stable attachment to smartphones, tablets and even laptops. The filter is compatible with many popular device models, including the iPhone, iPad, Samsung Galaxy Note, Google Pixel, Huawei and others. It can also be used with DSLR cameras that have a 37mm filter thread, making it an extremely versatile tool for photography enthusiasts. Adjusting the filter to your individual needs is intuitive and convenient. All you have to do is screw the filter onto the clamp, attach it to the lens and rotate it to achieve the desired effect. The filter's construction of high-quality optical glass and aluminium frame ensures its durability and resistance to daily use. Non-slip patterns and clear ND2-ND400 markings on the frame allow you to precisely control the amount of light. The Neewer FL-37 has an ultra-thin and lightweight design that makes the filter easy to carry and perfect for travelling. The set also comes with a handy storage box that protects the filter from damage and allows for immediate use anywhere, anytime.
