A close-up lens is a type of camera lens that allows the photographer to take pictures from a very close distance. It is also known as a macro lens or a ZOOM lens. A macro lens is designed to capture images of small objects, such as insects, flowers, and other tiny details. A ZOOM lens, on the other hand, allows the photographer to adjust the focal length of the lens, allowing them to capture images from a greater distance. Both types of lenses are essential for capturing close-up shots.
