Nisi Close Up Lens Kit NC II

The NiSi Close Up Lens Kit NC 77mm II (with 67mm and 72mm adapters) transforms a telephoto lens into a macro lens with a large working distance. It is 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 smaller minimum focal length. The magnification achieved depends on the focal length range of the lenses and is higher at longer focal lengths. At a focal length of 200mm, the magnification factor is close to 1:1.

When using a close-up lens, it is important to know the maximum and minimum distances at which you can focus, as you can only capture a correctly focused image within this range. The best working distance is between 22-30 cm. NiSi recommends using the close-up lens on telephoto lenses with an aperture of f/8-f/16 to achieve sharp details. The NiSi close-up lens is made of double optical correction glasses with apochromatic design and multi-nano coating to provide high resolution and natural colors without purple/green fringing both in focus and in the bokeh.
