The NiSi Close Up Lens Kit NC 77mm (with 67 and 72mm adaptors) allows a telephoto lens to function as a macro lens with a large working distance. It’s compatible with zoom or prime lenses in the focal length range of 70-300mm (full frame equivalent). The close-up lens is the most effective way to achieve a closer minimal focal distance. The magnification achieved depends on the focal range of lenses, it will be higher with longer focal lengths. The magnification will be close to 1:1 when you focus at 200mm.To use a close-up lens it is important to know the maximal and minimal distances at which you can focus because you will only be able to take a properly focused image within that range. The best working distance: 22-30cmWe recommend using the close-up lens on telephoto lenses with an aperture of f/8-f/16 to achieve the sharped details. NiSi’s Close-up lens is made of double optical corrective glasses with apochromatic design and muti-nano coating to give advanced resolution and a natural colour with almost no purple/green fringing both within focus and in bokehMounts on any lens with a 77mm thread with a focal length of 70 to 300mm Includes 67mm and 72mm adaptorsReview of NiSi Close-Up Lens Kit by Joni Niemelä
