On on the depth of field thing and getting closer, it was an off the cuff shot so I shot with what I had on the camera. I did shoot wide open at 2.8, but it was a 17-50 lens I had on and I shot at 50 or as near as. I didn't have the reach to get any closer.
Oops--looks like I missed the info you posted initially about the 17-50mm lens shooting wide open.
Glad to hear you'll continue to hang around. This is where a lot of the real learning comes in. You share a photograph and pay attention to the constructive criticism while disregarding comments that aren't important.
