The NiSi Close-up Lens Filter Kit NC 77mm (with 67mm & 72mm Adapters) consists of a Close-up Lens Filter that mounts on lenses with 77mm filter thread, as well as two adaptors that will enable the use of this lens filter on lenses with 67mm and 72mm threads respectively. When mounted, this close-up lens filter works like a magnifier to allow a telephoto lens to function as a macro lens. NISi recommends the use of this close-up lens filter with zoom or prime lenses in the focal length range of 70-300mm. The longer the focal length of the lens, the higher the magnification. (At 200mm, a magnification of close to 1:1 can be achieved). In addition, for obtaining sharp images, the optimal working distance between the lens and subject is between 22 to 30cm. The aNiSi Close-up lens filter is constructed with two apochromatic optical corrective glass and features a multi-nano coating to enable high resolution and natural colour with almost no purple/green fringing. The included 67 to 77mm and 72 to 77mm adapters permits the use of the close-up lens filter on camera lenses with smaller filter threads. A zippered pouch is also included for storing and transporting the entire kit.
