How to install a close-up mirror on a camera?

If you want to take macro photography with ordinary lenses (such as cheap 18-55 camera lenses), there are two methods. One is to find a filter-type close-up (the same caliber as the lens filter). This close-up is actually a convex lens-magnifying glass, which is usually 4 times or 8 times in size. The larger the multiple, the easier the picture is to be distorted. The second is to find a close-up ring (the same bayonet as the lens brand, preferably with electronic contacts), or take a close-up shot. The close-up contact ring will not produce distortion and the shooting effect is good.

In addition, there is a way to reverse the lens, which can even be used for ultra-macro photography. The lens reverse ring is also available for sale.
