Getting the Canon 100-400mm soon. My main interest is aviation photography namely close ups of civil aircraft. Any help please? I have read about it and someone mentioned the problems one might face.. quoting...
IS Mode 1 for stationary objects and single shot focus, made me mess up a moving duck shot, but most were right on .
IS Mode 1 and Servo sometimes has tendency to hunt, and I have found that it is good for objects coming toward or away from you but hard to use with left to right subjects. Why, because if you are panning and your center focus point leaves your subject it gets confused and can't find focus until you get on an object and this is hard because your viewfinder is a blur. The jury is still out on the new AI focus mode ( this is single shot until the subject moves and it goes servo)
IS Mode 2, the panning mode. This worked pretty well in the servo mode because by now I was learning how to cope somewhat. Out of 6 shots airborn I got two great and 1 good and 3 blurs. Here I found that Servo would loose the subject but if it came in to the view finder it focued on them again. What is the solution, I guess know your subject and how the fly, there pattern, Geese fly in a circle, Gulls do not know where they are going. Most big Birds have a direction. So I have picked the Gull as my practice bird. I figure if I can get good shots of them the other will be great.
Any help please?
Many thanks

I've used it, seen tens of thousands of shots taken with it and think very highly of this lens. It is, IMO, one of the best super-telephoto zooms around. It's also very reasonably priced, when compared with L primes.
The concerns you're describing are, really, more of a camera issue. I have completely abandoned the AI Servo mode, because of just such difficulties to a) learn to use it to the point of being able to employ this mode easily and effectively and b) because I do not need it as often as one should need it to, practically, profit from this feature.

Estelle,
your message made clear to me that you were referring to lens modes (1) and (2). I prefer to use setting (1) only. Really, I have completely forgotten about the mode switch on this lens and left it on (1) with excellent, all-around results.
I intend to experiment a little with it (2), in the future, based on what you said in this thread.
PS: I have copied and pasted this post in my reply to your message.
