The Sigma f1.4 series of lenses are superb; many think they are better than the Nikon equivalents. Sigma is NOT a substandard manufacturer. There does seem to be a difference between the lenses they've been designing over the past two years versus the ones from five years or longer ago though. You are stuck with your twin wants. To photo an air show, the Nikon 80-400mm is probably the best choice, but only by default. To photo birds in flight, you really need much more robust AF than what the 80-400mm gives and for that the Nikon 300mm f4 with TC-14E comes into it's own. You are being pulled into two different directions: zoom flexibility or fast AF. No lens will deliver both at your price point. You either wait for an updated 80-400mm AFS (which we've all been waiting about five years for now) or you spend the bucks for the 70-200mm f2.8-II and a TC-20E-III.
There's a joke that's really true when it comes to lenses. You can have any two of the following three qualities in a lens: Fast, Long, Cheap. You can't have all three qualities though, only two. So, which two are the most important for you?
