A bit about the photo. This was an exercise in depth of field for me. I took two photos at two different apertures to see the effects of depth of field on the angel. It turned out I used the one with a slightly larger depth of field for two reasons.
1) I had more of the angel in focus...but not the whole angel. I wanted to focus eyes on the details you see here. It was a conscience decision.
2) The smaller aperture also created a harsh octagon shaped bokeh. I knew this might happen because it is a know characteristic of this lens. In certain conditions when used below F2.8 you can create octogons instead of pleasing round dots in the bokeh behind your point of focus. I learned one situation when it happens. You can still see some it behind the angel to the left.
We'll be safe going home...and I hope you enjoyed the photo.
