I spent half an hour this morning hunting bees in flowers in my backyard, 70-300L on a bunch of extension tubes. MF only, stupidly low DOF, handheld, only thing useful was the IS, those bees move fast and you have to be lightning quick to find, follow, frame, focus before it moves to the next flower.
damn i want the 100L, would make my life so much easier...
ps, Tian, i love that apple-globe. Extra points if you managed to bite it that way rather than use a knife. (did you put the mid-Atlantic ridge there on purpose? not in exactly the right spot, but extra points anyway)
