70-200 2.8 IS II Image Stabilization modes

After reading another thread on whether to get this lens or not (I do have it BTW), there was mention of the IS or, IS2.
I know that the two modes are for up and down motion (IS1) and side to side motion (IS2).
Does anyone care to elaborate on the IS for this lens as far as optimal use of it?
Is the above correct about the IS modes?
Is there anything you would like to share regarding the lenses IS system from your own experiences?

Thanks.

The first mode is stabilization in both the vertical and horizontal axes, the second is stabilization in vertical only, for panning with moving objects.

Actually, the IS2 mold will only stabilize in the opposite direction of the panning direction. If filming a rocket taking off, it will stabilize only in the horizontal direction.

Yes. As woodzy said. Mode 1 is for still shots and stabilizes in both vertical and horizontal directions. Mode 2 is for panning and will automatically detect panning motion. The lens also has automatic tripod detection.

I did not know that. Is that a feature of the newer systems or has mode 2 always been that way?

Mode 2 has always worked that way... IS on a single axis.

...and turn off the IS if you are using a tripod.

I always forget to do this...

What advantage does mode 2 give? Why not just leave in mode 1 all the time?

Panning.

No. It is not necessary to turn IS off with this lens. It will turn IS off itself, in the absence of any movement, such as when the lens is locked down on a tripod.

In fact this is the case with all versions of Canon 70-200s with IS. Also all versions of 200/2, 300/2.8, 400/4, 400/2.8, 500/4, 600/4 and 800/5.6 with IS. In fact, IS can counteract fine vibrations such as mirror slap, that a tripod has no effect upon.

It is not the case and you should turn IS off manually when using the following on a tripod: 28-135, 24-105, 300/4, 100-400. If you don't turn off IS with these lenses locked down on a tripod, IS can go into sort of a feedback loop where it's actually causing movement rather than preventing it. You can see in the viewfinder when this occurs.

Not really sure about other lenses that have IS. No one from Canon has given an updated list in recent years. So I'd assume they need to be turned off.

Note that if shooting long exposures or video, you might want to turn off IS with any of the above lenses. IS can cause an image to "drift" slowly. And sometimes it "jumps". Neither is a problem with still photos at moderate shutter speeds. But they can be a problem if shooting long exposures or video.

Panning with moving subjects is often done to deliberately blur down the background. IS in Mode 1 can resist that blurring effect. Hence... Mode 2.

That would make sense. I was shooting go carts with the 70-200, and having a hard time getting "speed" blur, without using a horribly slow shutter speeds. The fact that I was in IS 1, may have been the problem. Thanks amphoto1.

So then how about sports?? Like soccer and basketball?

mine arrived yesterday... WOW!! BIG BOY LENS!

Anybody???
