1. DOF. This shot was taken with the excellent Canon 135mm f/2 L at f/2.5. "Ahah!" You say. "It's the shallow depth of field that makes all the difference. You can't do that with m4/3..." However, if you assume she's approximately 8 feet from the subjects, then the DOFMaster DOF calculator shows a DOF of about .15 feet. Indeed, that's shallow, but what if we increased the f-stop to f/5.6? Surely, that creates WAY too much DOF, right? Well, in fact the calculator shows a DOF of .34 feet. Hmmm. Not much difference after all and certainly not a difference that would have impacted this image.

You are confusing DOF with background blur. DOF is not really well visible on web sized images anyway. What creates that look and grabs the attention is the background blur. If you stop from f/2.5 to f/5.6, the (distant) background would be blurred much more (more than twice as much). This would create a distinctively different look.
