The Econo Auto Focus Extension Tube Set for Sony E-Mount Lenses from Vello allows your lens to focus closer than its normal minimum focus distance. They are compatible with Sony full-frame and APS-C cameras and Sony FE and E mount lenses. 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 set contains two extension tubes, one 10mm, and one 16mm. 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. 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 enable you to convert your E-mount lens into a macro lens while maintaining the lens' original optical quality.
