LS, I don't have any L lenses. But does the 200mm f2.8L have a better image quality than the 100-400? And if so, how bad would be the degradation compared to the 100-400? I'll have to take another look at Brian's info.


But yeah Dan, the 400mm f5.6L is a mighty fine value. It's just that the two for one idea looks tempting to me. And covered or not, that 400 is BIG!
