Brian Smith / Sony published another video about the cameras. Haven't finished watching it yet... first couple of minutes are marketing heavy, rest may be info light.
Edit... confirmed. I don't think I need to learn how many more times larger a full frame sensor is compared to 4/3. When he gets to discussing his images from Haiti it becomes more interesting.
PS: Zeiss ZM 18/4 fans, an image made with that lens is featured right at the very end of the video. No word on whether it's a cropped photo.
A dutch test of the A7r/ Metabones Smart adapter/ Canon TS-E lenses:
"...The results of the tests are convincing . The Alpha 7R has no problem with the Canon 24mm and 17mm TSE. The image remains sharp right into the corners and vignetting is the same as the EOS 5D at full shift.
The Sony A7R with Meta Bones adapter is currently the best choice for Canon photographers who need more megapixels and ultimate sharpness..."
For static subjects it looks more than merely acceptable; I've no idea if it has a continuous mode and if so, how well that works. I don't need to track a herd of rhinos coming at me but sometimes it is nice and more efficient to have AF-C if the camera can manage.
Frank and others have discovered that the a7r enhances lesser lenses, something Zeiss wrote about in a white paper: 'How to read MTF Curves Pt II'...
I mention it on occasion because it is a shining beacon of accuracy in the midst of a swamp of nonsense that you 'need the best lenses on high resolution sensors'. No, you don't. Optical truth is stranger than received wisdom. Which is fabulous news for fans of old lenses - ALL of them will have never looked better, and that is a scientific fact.

Philip,
The a7r doesn't enhance a lens,per se, but it does permit a lens' innate characteristics to show through. And of course, at 36MP it does out-resolve a lot of lenses, especially in the corners.
What I think is funny is that most people don't understand that exactly what you are saying is correct; they look at the pixel level of a lens test and see that a camera may exceed the performance of that particular lens, when in fact, that is really unimportant in most cases.
Only if you are intent on matching the resolving capabilities of the camera do new lenses become required with these high resolving sensors. For the rest of us, using the lenses we love for their particular rendering capabilities will meet our requirements, and do so with more pixels to employ for reproduction purposes.
