The two halves of the picture work so well together, the left with the motion blur of the bus, and the right with the sharp image of the two figures.
Thanks for your comment Yesbuts!
Looks as though the GXR is improving in your capabale hands. I think it's easier now to tell the difference between the GF1 & GXR shots.
Thanks, the GXR and GF1 are quite different but I think the biggest difference is in the lens and colors each camera produces. I would not want to decide for only one of them since both have their strengths and own character.
