Wild Life Lens Question.

I tried that and like it, but if you shoot small songbirds (robin and smaller) a lot, you want as much focal length as possible, and extra-speedy AF, both favoring the 400mm f/5.6. On the other hand, the 300mm f/4 IS has maximal magnification of 0.35x without modification, and this lens RULES for a butterfly or dragonfly photographer, and is great for wild large birds (eagles, etc) and for mammals.
