Macro lenses (also known as close-up lenses) are filter attachments that are simply screwed onto the respective lens. the effect is comparable to that of reading glasses and is also specified in diopters. They enable macro photography to be carried out with normal lenses. In contrast to macro converters, the close-up limit is not shortened. Only the magnification scale is changed. A great advantage is that there is almost no loss of light. Macro lenses are a good alternative to high-quality and sometimes very expensive macro lenses. They are also easy to transport and are lightweight. The close-up macro lens set is made of high-quality glass. The set includes a protective cover that protects the lenses from dirt and scratches.
