Description The Auto Focus Extension Tube Set (or the tube being used standalone) allows your lens to focus closer than its normal minimum focus distance. By placing distance between your camera body and lens, focusing distance is shortened and the effect of magnifying your subject is created. Extension tubes enable macro performance for lenses not otherwise able to focus that close, and are also suited for close-up portraiture. The Auto Focus Extension Tube Set for Canon EF/EF-S Mount Lens & DSLR Camera contains 2 extension tubes of 12mm and 25mm lengths. They can be used individually or together to create the desired magnification effect. For closer focusing use the larger extension tube or stack the tubes together. It is even possible to stack these tubes with others from another set. Extension tubes have no optical elements so they do not degrade the quality of your lenses. These are fully automatic extension tubes in that they are able to communicate all electronic functions from lens to camera including autofocus and auto exposure. They are built with metal lens mounts for durability and longevity and enable you to convert almost any lens into a macro lens at a fraction of the cost while maintaining the lens' original optical quality.
