I have a one year old Sony a7r with an Ommlite Canon-to-Sony adaptor. 
  
I am considering buying a Sony a7r II with Metabones adaptor.  I have read that many Canon lenses work in auto-focus mode with this combination (a7r II and Metabones), plus exif, etc..  Is this your experience?  For which of these lenses does it work?  
  
Canon 70-200 f/2.8L EF USM	 
Canon 17-40 f/4L  USM  
Canon EF-S 10-18mm f/4.5-5.6 IS STM Lens 
Canon EF 50mm 1.8 II Lens (plastic fantastic) 
Rokinon 8mm T/3.8 Fisheye Cine Lens for Canon
