. . . compare systems like the D800E/24-70G to the 5D3/24-70 II since the 24-70 II is such a great lens. In November, I shot the 5D2/24-70 II vs. the D3x/24-70G and much preferred the Canon files (mostly due to the lens). I am also confused by the reference to the P-Mpix score in an artcile about cameras since this score is lens related.

That's what it's all about - you always see a system performance.

Sure it is of academic interest to see which sensor performs better but the end of the day I am only interested in the results.

So on the Nikon you can use Nikon or 3rd party lenses. On Canon all of them with limitations plus Canon lenses of course.

Canon has introduced some astonishing lenses lately and with them together the system performance is virtually on a similar or even better level then the D800(E)

I posted some comparisons and only the 85 f/1.4 outpeformned my 5D II plus lenses.

the difference between the 5D II and III is negligible at lower ISOs - in fact the best performing lens  has a difference of 1 MPixel at DXO's rating (which is doubtable to say the least) But 1 Mpixel more is exactly the specified difference and thus it could make some sense even though the AA filter in the MK III is stronger and other test sites came to other results.

What I would like to say is that only the real world results count and I can only echo the OP - a IQ160 wins in every side by side comparison simply due to it's shier pixel count in combination with the larger sensor. If I shift and stitch to the virtual sensor size of the IQ160 (which is possible with the TS-E 17 and 90 I own) I get stunning results which should be close to the IQ160 back in pixel count and (virtual) sensor size but the most determining factor are the lenses used.

It's all about the lenses and the cameras nearly don't count - cameras are disposals - lenses are keepers. We are not at the end of the sensor development and Nikon did a great job with introducing the D800(E) - yet they have some homework at their lenses and maybe their lens mount too

First off, I slightly misunderstood the OP's commentary as well as the bent of the article. I'm now on the same page but I do see things a tad different.

While system vs. system is a excruciatingly practical measure when staying within brand, and I can discuss it on that level too, what about those who are into 3rd party lenses? For example, I'm very partial to Zeiss lenses while others may prefer Sigma et al. Many of these lenses can be purchased in either mount. Many of them are just as good as the brand lenses. So, which mount?

As Slideshow Bob mentioned, good lenses are a given. I mean this was being said about 21 MP when the 1Ds mkIII and 5D2 were released.

If I win the lottery (or the price of MF falls), the IQ180 will be my cam of choice. No doubt. But until then, I have to be interested and tuned into what the "budget" format (in this case, 35mm) has to offer.
