The Caruba Reverse Adapter Macro Coupler 58mm 67mm is designed to allow you to mount a second lens upside down on the original lens. This technique is used in macro photography to obtain high quality macro images with high resolution and sharpness. Macro photography can be achieved by mounting a lens upside down on the standard mounted lens. You simply screw this macro coupler adapter ring into the filter thread of both lenses.
The magnification factor is calculated by dividing the focal length of the normally mounted lens by the focal length of the inverted lens (for example, when an 18mm lens is mounted upside down on a 300mm lens, the reproduction ratio is 16: 1). Using auto focus is not recommended if the first lens is not of the internal focus type, as the extra weight of the reverse mounted lens can damage the auto focus mechanism. The working distance is considerably less than normal. ,
