My Nikon 18-35G was tack sharp on the D800E.
I think the problem is mainly down to two things: refelctions runining contrast, and diffraction.
Regarding reflections, that has to do with the adapter, but not manufacturing tolerances. Flocking and masking is necessary with most adapters on the A7r, many threads here describe it.
Regarding diffraction:
The Nikon image was shot at f/7.1, ISO 100 and shutter speed 1/320. The Sony image was shot at ISO 100 and shutter speed 1/125 in the same light, so the aperture was probably around f/11 where you visibly start losing micro contrast on the A7r. Accurately controlling aperture is a problem with adapted G lenses, and the best bet is to use the metering to determine how many stops you are from wide open.
Good luck, don't give up on the A7r !
