Conurus have introduced a new lens adapter in conjunction with Metabones for use on Sony NEX bodies. This unique adapter allows mounting of Canon EF lenses to the Sony E-mount. The unique part is that lenses retain both electronic aperture control as well as IS capabilities. However, autofocus is not supported. Since the aperture closes during metering (assuming you're using something other than the maximum aperture), there's an "Open Aperture" button (opposite of DOF Preview). US$400.
