The new Kenko Full Frame E-mount compatible Extension tube set is now shipping in Japan. Don’t know when these will be available in the rest of the world and I have not found any preorder option yet.
Here is the official Press Text from Kenko:
Kenko extension tubes are precisely made in Japan in order to guarantee the best quality and long life of the product. Simple construction matches APC-S size αmirrorless and Full Frame E-mount SONY cameras.
Attaching between camera and lens DG Extension tube will change your lens into macro lens without large investments in additional optical equipment. You will get close up image, the one you can not shoot with lens only.The wider the ring, the shorter focusing distance to the object. That is why Kenko Extension Tube Set comes with 10mm and 16mm tube rings. You can use it separately, or together.
Kenko Extension Tubes for Full Frame SONY E-mount mirrorless cameras have electronic contacts to provide Auto Focus and EXIF data corresponding between camera and lenses.

Kenko adopted electrostatic ﬂocking ﬁnish on the inner surface of the extension ring – the most eﬀective technology ever known to minimize internal reﬂections, romping light rays and ﬂares. Kenko electrostatic ﬂocking is a mass of short (0.3mm -0.5mm) synthetic ﬁbers that are adhered by static electricity on the fabric and reinforced by coating that prevents ﬁbers from falling out.
