You may miss the point when you come closer to a flower or other small object to take a picture of it. Haven't you had such an experience?At such times, "Close-up lens" mounted on the lens will enable close-up shooting.
The close-up lens mounted on the lens will shorten the minimum focus distance, enabling you to, in effect, come closer to an object for close-up photography.
Unlike a zoom lens with a macro, it can be used in the entire zoom area. You can take a picture at any magnification by zooming even at the same distance from the object.
