The Econo Auto Focus Extension Tube Set for Micro Four Thirds Mount from Vello 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 Econo Auto Focus Extension Tube Set for Micro Four Thirds Mount contains two extension tubes of 10mm and 16mm 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 two 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 electronic functions from lens to camera including autofocus and auto exposure. They are ultra lightweight 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.
