This 58mm Canon EF/EF-S mount Macro Lens Reverse Adapter Rings is threaded on one side to fit the filter thread of your lens, the other side is mounted onto the Canon EF/EF-S mount DSLR camera body. With the lens being reversed, it greatly increases the lens macro reproduction range capabilities, this saves your cost of buying an expensive macro lens for macro photography.
Steps of use:
1. Take out your lens from your Canon DSLR camera body.
2. Mount the adapter ring to your Canon DSLR camera body.
3. Reverse your lens with 58mm filter thread and screw it to the adapter ring until it is tight.
Note: Autofocus, automatic diaphragm (AE metering), and other functions dependent on communication between camera body and lens will be disrupted with this reverse ring mounting on the camera body.
