HI
I use a canon 100-400is lens and I have been told that you have to turn the IS off when its on a tripod because its not moving which i can understand, but I was thinking of using it on a monopod for helicopters in front of you and things like that do you still have to turn it off for that or change the mode.
Cheers John.

I was once advised to turn mine off full stop as it slows down the auto focus , and I have found this to be true.

Interesting question John as I've been playing about with exactly that recently. From my in-depth results obtained on Wednesday, I can honestly say it does make a difference to me with the IS switched off unless the subject is moving reasonably fast (say a Sea King on approach to 23). I have noticed however, that with IS switched on and leaning on the wooden fence, anything static comes out fine 
The biggest improvement in my shots recently has come from locking off the 100-400 and concentrating on my panning...

I don't use the 100-400 but my 70-200's IS will shut off if it detects its on a tripod, I think it is a slighty newer IS generation from that used in the 100-400. That said I still tend to switch it off when mounted.
The 70-200 has two modes stabalisation in vertical and horizontal planes or Vertical only (to aid panning). The biggest difference I've noticed to my shots lately is taking the UV filters off my lenses.

I use Pentax which has the IS built into the camera. However they advise that this be switched off when usin a tripod
