So, this is a pixel peeping 100% view that takes no account of the resolution of the different camera?  In other words, it is only useful for examining per pixel acuity? Which will be heavily influenced by in-camera settings.

I have been on DPreview forums for over 20 years and I have seen plenty of image quality comparisons. If you compare different cameras at different reproduction sizes, it simply doesn't give any kind of realistic image quality comparison.   Images have to compared at identical sizes to make any sense.

A 5MP and a 100MP image may look reasonably similar at 100% but there is no comparison in a 60"x40" print.

There is no ideal way to do these comparisons over the web, you can't beat having the original files/prints to eyeball but I am still convinced that the most revealing way is to print out the files, then scan (or re-photograph) small sections.

When Chromelight and I did our SD14 article all those years ago, we scanned small sections of large prints at high resolution.  That really provide a good impression of relative performance and what a big print from the files would look like. Even with relatively inexpensive scanners, because you were making effectively a 1:1 scan, there was no issue about scanner defects. A scanner designed to scan and blow up small negs, is very happy scanning a print at actual size.

Still the most convincing way to compare files. And when it comes to comparing detail, you could quite happily do away with the scanner and just photograph sections of the print with another camera.
