APEXEL USA INC.: The APEXEL 4K HD 6 in 1 Filter Lens Kit includes a 16mm HD wide lens for capturing more of landscapes and large group photos, a 10x macro lens for detailed close-up shots of tiny objects, and a CPL lens for enhancing color saturation by removing unwanted reflections from non-metallic surfaces like water and glass. The kit also includes Grad blue and Grad gray filters that add color to specific parts of a photograph without affecting other parts, and an ND8 filter that reduces the amount of light reaching the camera sensor. The ND8 filter is ideal for achieving motion blur in waterfalls, clouds, and other moving objects or for reducing depth of field in bright conditions without affecting color rendition. Note that the wide-angle and macro lenses are screwed together and must be unscrewed to use the macro lens.
