If you are Canon-inclined I highly recommend the 50/2.5 Compact Macro. They recently went out of production. I am planning on picking up another copy as mine will no longer focus manually. It is so good optically that I don't mind working around that. Canon 5D2, EF 50/2.5. Adobe Lightroom adjustments.
I'm not sure what is throwing the square on a stick shadow near center. Might be the pedestrian crossing sign at the intersection out of frame to camera left. Canon 5D2, EF 70-200/2.8. Cropped 5x4, Adobe Lightroom adjustments.
