I have both of the Zeiss Planar's and attached them to my A7r with a Novoflex adapter. I was surprised by the poor images that showed a definite out of focus area on the left hand side - very abrupt! I had never seen that before on my 800e so shot the same images with those lenses on my Nikon (same focus point, same f stop) and was really surprise at how much better they looked. I'm attributing this to a faulty adapter. If one is bad then other's also can be...... testing this stuff is really important....
