Was looking at this new lens from Canon.
EF S f4-5.6 IS USM
Looks a cracking lens. But, I see the spec shows the IS being turned off if it detects horizontal or vertical panning. Doesn't this contradict the whole purpose behind image stabilization? I thought the whole idea was that it would stabilise your image while you panned - sort of.
I want to use it for motor sport, but if the IS system is shut down as I pan across the plane of the cars passing in front of me, I'd be as well sticking with my 75-300 lens I already have. Or would I?
