This macro reverse adapter ring is made of aluminum
It allows your lens to be mounted onto the camera body in its reverse position
With the lens being reversed, the lens works like a magnifying glass and your lens becomes a macro lens, this saves your cost of buying an expensive macro lens
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
It is compatible with any Canon EF/EF-S mount DSLR camera + Any lenses with 58mm filter thread. Please verify your camera's lens thread size before ordering. Your camera's lens thread size will be marked somewhere on the lens barrel or printed underneath your lens cap.
