Nice frame and a crazy stunt by the two guys :-). I found your site and this pic in a message board thread about the Bigma's sharpness and if I remember correctly this was supposed to prove the superiority of Canon's 100-400. Please don't take an offense, but the trees, lamp and plant on the lamp in the background are more disastrously unsharp than on my compact (pentax Optio MX4). It's not your fault, it's the lens. If Bigma is really less sharp, I wonder why it's even called a lens :-). I've seen a few shots from Bigma and they looked much better. So it corroborates my belief that Canon optics, in particular those from the analog era, are overhyped and not worth the money they cost.
