Neewer FL-45 67mm ND Phone Filter Kit

The Neewer FL-45 67mm ND Phone Filter Kit is a specialized clip-on filter system designed to bring celestial and solar photography within reach of any smartphone user. Built with high-quality optical glass and a polymer safety filter film measuring just 0.25mm thick, the kit delivers an optical density of 3.8—equivalent to a 15.6-stop light reduction that allows only 0.0032% of light through. This extreme density makes it possible to safely photograph the sun, solar eclipses, and other intensely bright astronomical events directly through your phone's camera without risking sensor damage.

The clip-on mechanism accommodates smartphones up to 13mm thick, so most devices can be used even with a protective case in place. Beyond basic filtering, the kit includes a cold shoe mount for attaching compatible Neewer LED video lights or wireless microphones, and a threaded 67mm adapter that opens the door to stacking additional filters. The standard 67mm thread size makes it easy to integrate into existing filter collections. At just 3.5 ounces with compact dimensions, the entire kit slips easily into a pocket or camera bag, making it a practical companion for eclipse chasers and astrophotography enthusiasts who prefer to travel light.
