This NiSi 77mm Close-Up Lens offers the ability to achieve macro-like results with camera lenses that feature focal lengths from 70mm to 300mm and have 77mm, 72mm, or 67mm 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 200mm focal length, this close-up lens provides an approximate 1:1 magnification.
The lens in this 77mm 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 step-up ring that permits the use of the close-up lens on a camera lens with 72mm front filter threads, a step-up ring that permits the use of the close-up lens on a camera lens with 67mm front filter threads, and a padded pouch to store or transport the entire 77mm Close-Up NC Lens Kit.
