It very likely will perform better in ISO tests at the largely irrelevant pixel level but at 50% zoom or at print resolutions it will probably do about as well, for all practical purposes... treat it as a sampling device at low ISO and an oversampling device at higher ISO. Look at the DXO ISO scores of the D610 and the D800E and remember that no AA filter means less sharpening needed, which helps the appearance of higher ISO files...The A7 is supposed to be faster in cAF and in operation, and will perform better at high ISO, both qualities I do not need, so my vote is for the A7r which sees to be better in every other aspects (let alone the price).
If the problematic color cast showing up in the corners of the Nex-7 with wide angle legacy lenses is due to the angle at which the light rays strike the sensor, then I fear that gape less micro lenses won't help a lot to solve the problem. Gape less micro lenses may just be the consequence of the higher pixels density resulting from the pixels increase.This sounds like the a7 doesn't use the same on-sensor micro-lens design as the a7r
"Differing from the Sony Alpha a7, the Alpha a7R with its omitted low-pass filter, gapless lens design sensor and contrast-detection AF provides the utmost in high-resolution, finely detailed capture".

Not sure you can use that as an example. We have to assume in a comparison that each pixel is collecting a certain level of tonal value. I would not assume that for a phone camera with zillions of tiny and ineffectual pixels.Ben, Simple answer is NO.
For an stark example look at the 41MP phone vs any real camera images with a much lower pixel count.
I am not sure about that, Ben.One thing is for certain, the prices of alt lenses, already high, is going to absolutely sky rocket!
The A7R has an off-set micro-lenses array which should, in theory, offer some improvement.
I have checked the images tacken with the Summicron 28 and they are not sharp across the frame, not at all for what I can see.The A7R has an off-set micro-lenses array which should, in theory, offer some improvement.
Either way, based on these tests by Ron, I find the results quite promising. I am not overly concerned with the vignetting since it is easily address in post and, possibly, in camera. What I find very promising is that the images look sharp across the frame, which was my biggest grip with Leica wides on the NEX7.
The 28 Summicron has significant field curvature and (even on the M9) needs to be stopped down to at least f5.6 before it is sharp across the frame.I have checked the images tacken with the Summicron 28 and they are not sharp across the frame, not at all for what I can see.
May be the A7R will be a better performer in this regard, hopefully..
Looking at the infinity shots I cannot find anything sharp in the corners/borders at any distance, I do not think it is a matter of field curvature.The 28 Summicron has significant field curvature and (even on the M9) needs to be stopped down to at least f5.6 before it is sharp across the frame.
