It seems like a very nice lens. I have to ask myself though, if his only other choice were using the 100-400 how much different would these shots look? Sure the ISO8000 shots wouldn't have been possible at f/5.6. I guess what I'm saying is that it seems like a lot of money to gain one stop and IQ. This lens is 10x the cost of the 100-400, but is it 10x a better lens? It will be very interesting to see what an updated 100-400 will bring.
It gets more expensive than improvement in IQ all the time.
50 1.8 is 100, the 50mm 1.4 is 400 and the 50mm 1.2 is 1400... is it 14 times better? definetly not.
the 75-300mm is 100, the 70-300mm IS USM is like 500, the 70-300mm L is 1400 bucks... again, 14x better?
