Couple interesting points, I thought:
* New Canon 24-70 2.8 MKII bested the older Nikon 24-70 2.8 in the optical bench test (not mounted on any cameras.)
Newer lens beats older lens. Whilst good news, it's what you'd hope for.
* On the D800E, both the Nikon and the Tamron at f/2.8 resolved more than the Canon at f/4.
Higher resolution cameras resolves more than lower resolution camera with similar lenses. Again, this is what I'd expect and hope for.
* Worse lenses on a higher-res sensor is almost always going to be better (from a resolution standpoint) than great lenses on a lower-res sensor.
I don't know how many pixels it takes in a camera to exceed the resolution of these lenses, but I'm confident that the lenses still have the edge. That being the case, then this is also the result you'd expect.
Does anyone have figures for the theoretical maximum resolution of any of these lenses (in megapixels)?
I'd guess diffraction is the limiting factor, it'll enter the picture before any other effect for these modern lenses, at least in the central part of image.
