But the real world end result of that tech spec talk is that you cannot tell the difference. I've processed over 23k of photo's from my A77, 7k from my A580 and 9k off my D7000 (which share the same sensor) meaning I think I've got enough experience of both without needing to look at some graphs or some pixel peeping CSI software that means nothing to me or has any effect on my day to day use.
I can easily without any hassle at all get as much detail out of either of the Sony's as I can when using the Nikon (that's the only bit that matters to me personally), whether that changes when you get to FF or not I don't know as I don't have any experience of them but I have to admit to only reading a small portion of that link you provided before I closed it because such info holds zero interest to me and frankly sucks the life out of me.
Hopefully someone else may find it useful though.
