The Opteka Auto Focus Macro Extension Tube 25mm is designed to enable a lens to focus closer than its normal set minimum focusing distance.Getting closer has the effect of magnifying your subject (making it appear larger in the viewfinder and in your pictures). It is exceptionally useful for macro photography, enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality.

The extension tube have no optics. It's mounted in between the camera body and lens to create more distance between the lens and shutter plane.By moving the lens father away from the film or CCD sensor in the camera, the lens is forced to focus much closer than normal. The greater the length of the extension tube, the closer the lens can focus.It is with electronic contacts,which make it support automatic focusing,automatic exposure,etc.
