maybe it's like that movie "brewster's millions". that's a good one.
i agree, you should slow down.
also, that tokina can't take filters, and has a screwy manual focus system, but if that stuff doesn't bother you... i'd rather have the 17-40, but that's just me. if you can't see the value in the 16-35 over something like the 17-40 or tokina you shouldn't buy it.
