This NiSi 58mm Close-Up Lens Kit offers the ability to achieve macro-like results with camera lenses that feature focal lengths from 35 to 250mm and have 58, 52, or 49mm front filter threads. A close-up lens is a magnifier that optically decreases the focal length of a camera lens placed behind it. This effect lessens the minimum focus distance between the camera lens and a subject. Magnification can then be obtained by decreasing the distance between the subject and the combined camera lens and close-up lens. On lenses with or set to a 120mm focal length, this close-up lens provides an approximate 1:1 magnification.

The lens in this 58mm Close-Up NC Lens Kit is constructed from two apochromatic optical glass elements, which include NiSi Nano coatings for enhanced clarity as well as more effective prevention of internal ghosting, reflections, and chromatic aberrations. Also included are a 49 to 58mm step-up and 52 to 58mm step-up ring set that permits the use of the close-up lens on other camera lenses with smaller filter threads, front and rear caps, and a pouch to store or transport the entire 58mm Close-Up NC Lens Kit.
