EF Adapter with Aperture control
The Metabones adaptor is probably the only real game in town at the moment for EF/EF-S lenses with aperture control on the E-mount -- here: http://www.metabones.com/ .
It's been out of stock for awhile -- I'm currently waiting for mine (in transit) but if you search the forum for metabones or conurus, you'll see a number of user reports.
