A7R and L lenses go like a slightly unbalanced bread and butter ... the TS-E 17mm has practically not come off my A7R since the day I got it. You will be faced with a few issues (already discussed earlier in this thread) but results are outstanding.
I do however still have and use my 5D2, when auto focusing is actually important (zoos, activities, etc). A7R with L lenses is great for stationary subjects or tripod-bound work.
One note, I originally had my MB adapter completely flocked with Edmunds paper, to reduce glare within its optical path. It mostly took care of the problem, until I got TS-E 17mm. Any up/down shift over 7mm exhibited vignetting, and a tilt in direction of shift (even if shift is 2mm and tilt is 2 degrees) showed severe vignetting as well. I got so fed up with it I ripped out the flock paper from top and bottom of MB's chamber, which allowed me to use the lens unrestricted (without any glare). It unfortunately made it nearly impossible to use my 24-70mm MK2 (which is my second most used lens on A7R) as lateral flare got painful again.
Also maybe it's due to humidity here in Florida, but the Edmunds paper was unsticking from the adapter on its own anyway (which may have contributed to the problem).
I ordered a matte black pen and may try something with it. I'm actually thinking of getting a second Metabones adapter so I have one partially flocked for TS-E 17 and one fully flocked for other lenses
Just purchased an A7R with MetabonesIII adapter to add to my 5D MkIII and L lenses. I've been impressed with what I have read here and elsewhere. I mainly do Landscape so I am looking forward to using my 17mm TS-E and 16-35 II on the A7R.
I am keen to hear what people think of this camera and if the 5D MkIII survived in your camera bag for long after buying the A7R.
