I understand IS and I can see the IS working on my 24-105 L. My questions is

If you were taking a picture of a subject that doesnt keep still, or, you needed to aim, focus and shoot rapidly is it better to have IS switched off.
An example would be if you were taking a wildlife shot from a boat. The boat is floating down a calm river so there isnt much rocking etc, however, the bird / wildlife is on the riverbank. Would the IS function hinder the shot. Although it only takes a nano second to stabilize would this have a negative effect to using a fast shutter speed as the first couple of frames will be taken as the IS is settling.....
 
Unless you are doing a grap shot The IS is probably engaging whilst you are composing the shot and focusing. Also try hand holding a long lens hand held with IS on and off and you'll see the difference it makes
 
In my experience, no.
In fact given the scenario you describe I still think it would help the shot - IS is pretty quick these days so even a little rocking will be helped by it.
 
I'd say no too. Even the 55-250 is a toughie to hold still at 250mm. I only ever turn the IS off for tripod mount shots...
 
Nikon VR has 2 options:

1 for a moving subject/ slow shutter speed
2 if you are moving

Canon does too,
Mode 1 for stationary objects (or close enough to stationary not to make a difference)
Mode 2 for panning (horizontal stabilisation is disabled)

IS and VR are identical in this regard :)

Not the 24-105. It has IS on or off, thats it.

That's because it's an older IS design, newer lenses have the panning feature, tripod recognition and a greater stability, up to 3 and even 4 stops over the older 2 stop stabilisation.
 
The 4 stop IS on the 55-250 has on or off only, but works out if you're panning and deals with it (apparently, so the manual said. Seems to work too).

Yeah fair enough, I just thought the OP was talking about a theoretical situation with any IS lens and was confirming that Canon's IS is the same as Nikon's :)

If you are using a fast shutter speed surely you don't need the IS anyway?
 
Hi, (I've been using VR lenses for two years -24-120VR then 18-200VR),
VR (like IS) is inefficient and traitorous at high speed (or with the camera on a tripod), you must disable it or your pictures will be often blurry.

I didn't realise some were fully 'automatic', it's a brand new lens though is't it? So I guess it will be the standard in the future.
 
Yeah I think it was released only in about the past 8 months.
