It looks as though, with a few caveats, the A7r is a serious contender as a second body for owners of either Canon or Leica systems and, for early adopters of the A7r, Canon glass might be a cost effective stopgap while waiting for the FE lens system to fill out.
Yes, Bob, The Canon Glass and the A7r through the Metabone Mark III adapter is awesome. I am using an TSE-24 Mark III with the A7r and the focus peaking is a blessing. It makes the whole process of focusing while the lens is titled a much more enjoyable experience. I also tested with the 24-105L, 50mm F1.8 II and the Tamron 70-200 F2.8 VC. All works great.
