it's an old example of describing a very technical phenomena with enigmatic and mostly meaningless terms because it's understood that the audience will not understand.
I love this description and I suspect this thread will be full of great images which many will likely disagree upon as to how well they fit into this enigmatic term. Nevertheless, I will play.
Subjectively, I have traditionally associated this idea with mostly larger format images, seldom small format. Medium format film and up perhaps. This likely has to do with the qualities mentioned above regarding detail, sharpness and focus transitions. Other mysterious, almost meaningless adjectivesI associate with the look are "richness" and "fullness". Obvious sound analogy would be the rich, full sound of analog vs the thin, almost hollow sound of digital - a grand stereotype that does not always hold true of course.
Surprisingly to me though, I have seen what appears to my eyes to display this quality in even APS format, most recently with the lens of the Fuji x100. I have also seen it with the Leica Summicron R 50. I tend to prefer shooting at around F4 so I suspect there is something to using a moderately bright F-stop.
