Unique function: Light pollution will not only adversely affect the quality of night city and architectural photos, but also adversely affect scientific astrophotography in urban areas. The K&F Concept circular filter helps reduce unnecessary light pollution effects, thereby making photos more contrast and sharp. 

Material: K&F Concept double-sided nano-coated natural night filter adopts waterproof and scratch-resistant technology, bringing high definition, low reflectivity and no vignetting. High quality: The most common light pollution wavelength in the night sky is blocked, and the color of the entire scene is significantly improved. 

SuperSlim: The 3.8mm ultra-thin frame design and Super Aviation aluminum alloy material will not create vignetting on any brand of camera.
