Keep in mind that A7r does not EFCS (Electronic First Curtain Shutter). Due to this you will experience "shutter shock" in images shoot with very common shutter speeds from 1/200s to 1/2s. You can simulate A7r shutter with A7 by disabling the EFCS from menu. Problem when zooming to 100% will be of course magnified with A7r as pixels are smaller.
I have 2xA7 (modified thin filter cover glass), A7r (standard filter cover glass) and A7mkII (standard filter cover glass). Any time I go photographing I need to plan used lenses so that with A7r I will not use longer lens than 50mm. I'm shooting almost 100% from tripod, and 50mm is longest I'm conformatable shooting with A7r. With 85mm I can get sharp images if I apply lots of weight to camera (when it's on top of tripod) and shoot landscape images, but portrait shots are hard to make 100% sure so that I avoid motion blur caused by "shutter shock" - this is with large high quality ballhead and Gitzo 3-series tripod, with small ball head and Gitzo traveler already 50mm will have visible "shutter shock" in most of images.
A7r mkII (or A7r mkIII) is better camera in every possible way, unfortunately comes with matching pricetag. When one does not need IBIS or improved AF, the price is just too much for EFCS and backlit CMOS (36mpix vs 42mpix is so small difference that I don't count it as difference).

The shutter shock issue with the A7r is worse in the portrait rather than the landscape orientation. But there are ways to minimize the affects.
Below are images taken with my tripod mounted lenses and A7r (no they are not taken with the Zeiss 35mm f1.4 lens):
