Does anyone have any practical experience of using a Canon 100-400 plus an Extender for air show photography?
We have a customer at www.LensesForHire.co.uk who wants to hire a 100-400 to take to the big show at RAF Fairford in July, which I'm sure is a good choice, but he's not sure whether an Extender would be a good idea.
Pro: Extra reach.
Con: Lower quality, loss of autofocus (camera=400D).
I think the trade-off is that the cons are probably worth tolerating if (a) the extra reach is necessary and (b) the loss of autofocus is manageable. What would you advise? 1.4x Extender? 2x Extender? Or neither?
