The EXT-SFED2 Auto Focus Extension Tube Set for Sony E-Mount Lenses from Vello consists of a 10 and a 16mm tube that enable a normal lens to be used for macro photography. By placing a tube between the lens and camera body, it reduces the minimum focusing distance of the lens, so it creates a magnifying effect. Each tube can be used individually or combined for greater magnification and, also, these tubes are suitable for both full-frame and APS-C-format cameras and lenses.
The tubes are of a lightweight design and made with durable metal mounts, which can withstand the rigors of constant use. They are also equipped with electronic contacts, which communicates with the camera body and maintains autofocus and auto exposure of your lenses. There are no optical elements inside the tubes, so there is no degradation of quality in your glass.
