Stealth-Gear Extreme reversing ring 67 mm for Canon
The Stealth-Gear Extreme Reverse Ring allows you to reverse photograph with a lens that has a filter size of 67 mm. One side of the ring has a connector for the Canon EF Lensmount and on the other side of the ring has a threaded connection. This way you can attach your lens upside down on your Canon body. Also with a “normal” lens are then spectacular macro pictures to take!
Using a reversing ring
When using a reversing ring, a lens is used the other way around than is normally the case. The reversing ring is on one side fitted with a threaded thread that fits in the filter thread of the lens. On the other hand, the reversing ring has a bayonet socket that fits on the body of your camera. This also means that the contacts of the lens mount do not make contact with the body of your camera. Therefore, your camera cannot send commands to the lens. Functions such as the Aufofocus and the control of an electronic aperture of your lens are therefore void.
