that must have been that crowd i saw farther down the dyke(eastward), i didn't even bother heading down there( so many cameras down there). damn that light was awesome, eh.
can't you just grab a 400mm off the shelf?

seriously though, i think the 400mm has the huge advantage of just hand hold and shoot. don't think you easily do that with the 500mm?
so, where would you like to shoot next week, lol.
