An affordable tool for macro photography. The swivel ring allows a 52mm threaded lens to be attached to the front of a lens with a 52mm thread, enabling macro photography.

A lens reversal adapter allows you to attach one lens upside down to the front of another lens. This technique is used in macro photography when you want to achieve higher magnification than normal.
There is a 52mm male thread on each side of the adapter.
The magnification ratio is calculated by dividing the focal length of the normally mounted lens by the focal length of the upside-down lens (for example, when an 18mm lens is mounted upside-down on a 300mm lens, the magnification ratio is 16:1).
NOTE: It is not recommended to use autofocus if the first lens is not an internal focus type, as the extra weight of the lens mounted upside down may damage the autofocus mechanism. The working distance will be significantly shorter than normal.
Then just shoot in a completely new style. Of course, this reverse shooting method is best started by shooting completely still subjects, as the subject may need to be right at the back of the lens before the image is sharp.
