Techart again updated the firmware for their [shoplink 39860 ebay]Contax G to E-mount autofocus adapter (available here on eBay)[/shoplink]. With the new adapter autofocus speed has been again improved! You can download the firmware on Google Play (Click here) or iTunes (Click here). Techart Contax page:

Chad Wadsworth already tested the new version and writes:

As of revision 2.1.0, released in October, 2015, the performance is rock solid with AF speed on both my lenses (45/2 and 90/2.8) that rivals a native lens – yes you read that correctly. I’ve noticed some minor hunting in low contrast / low light subjects but nothing major and native FE lenses frequently do the same. AF accuracy is spot on and the MF implementation now works as it used to, meaning that you can engage MF at any time by adjusting the small focus dial on the adapter. This is a major achievement by TecArt and finally makes these lenses viable options that I would feel confident shooting even for paid work.

And there are two videos posted on SonyAlphaCameras do show how good and how noisy(!) the adapter works on the Sony A7rII.

These are the Contax Full Frame lenses you can use on the A7-A7r-A7s and APS-C E-mount camera with full autofocus and electronic aperture control:
