Re: Tokina 400mm f/5.6 AT-X - opinions???

I own both the Tokina ATX-AF and the Sigma Apo Macro 5,6/400. Of course the Sigma is the winner, sharp wide open, no CA. But it is a lot bigger too, so when I travel for longer periods, want to travel light, but not without a 400, I do find myself taking the Tokina and trade the nuisance of being bulky for the nuisance of postprocessing. At 8-11 the Tokina is certainly sharp but removing CA (pronounced purple edges on harsh contrasts) is inevitable.
