This 52mm 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.

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 52mm filter thread and screw it to the adapter ring until it is tight.
