Reverse mounting ring. By using this ring, we can connect two lenses. We screw a ring of suitable diameter onto the lens mounted on the camera (at the point where the filter is attached). We need to check the diameter of the second lens (at the point where the filter is attached), which we want to connect to the lens mounted on the camera. In this way, we can connect two lenses together (the second one is reversed, i.e., with the front lens facing the camera body). This is applicable for MACRO PHOTOGRAPHY. The MACRO magnification scale depends on the focal length of the connected lenses.

The auction item is new reverse support rings from the excellent company KIWI. These are not poor-quality plastic fakes. The ring is made of metal (aluminum), high quality, with rings made of a special metal alloy. It is lightweight and at the same time resistant to thread wear, black, specially chemically blackened.

The adapters have coatings that prevent repeated screwing and unscrewing from damaging the lens. What should be emphasized about these adapters is their high quality and precision of construction.
