The NiSi Close Up Lens Kit NC 77mm II (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.
