Hi Jack,
I know you like the 80-400. I am thinking of getting one instead of the 70-200VR but the autofocus speed concerns me. I've done a fair bit of birds in flight with the 70-300 and the autofocus speed I find to be poor. Is this lens around the same? Have you tried any birds in flight? It would seem that a train is alot easier since it is on a constant trajectory.
Thanks
Tom
Tom, I have done very little shooting of birds in flight. However, what I've found with this lens is, it does just fine after the 'initial' focus, e.g., once I've focused on the subject that is moving, it has no problem tracking the subject. Admittedly, I've only shot birds a few times, so I would feel more confortable if you could try the lens for yourself In all other aspects though, I have no problem recommending this lens. If I can get time in the next couple of days, maybe I can do a few test runs shooting birds.
Here's an image shot at night and it had no problem...

HTH!
