OSS Mode question

[RacingManiac]

I've not had a lot of experiences with lenses with OSS mode, but now that I have 2(70-200 GII and 200-600G), I want to better understand their functions. So I understand the 3 OSS modes are:
1: Stills

2: Panning

3: Random direction, or something like that

My question is for something like Mode 2, for Panning, is it limited to panning in a particularly orientation/direction, or does it just compensate for panning as in intentional movement in 1 axis, regardless which direction it is?

2 examples, if I am shooting from an elevated position(say a grand stand of a race track), with the subject coming towards me, but because I am elevated, to pan I am doing more of a top to bottom motion(or maybe diagonal) as opposed to normal side to side. The other example, maybe if I am shooting with a vert grip, and my frame is portrait oriented but I am panning side to side.

To be most effective with OSS use, would Mode 2 still be the one to use, or would this be more like Mode 3?

I experimented a bit with that and it seemed like the mode 2 panning works in any direction. It did hesitate a bit after starting a pan, like it needs to see the continuous motion before stabilizing in the other direction. Hard to test, though.

As far as I can tell mode 3 works exactly like mode 1, only it does not try to stabilize the EVF. Both modes are useless for panning.

In general I disable IS when my subject is moving. Of course my subjects are quite fast (BIF) and my shutter speeds are high. Hence I don't really need stabilization. The upside of disabling it altogether is that it will never try to compensate motion that actually was me intentionally tracking the subject. Which otherwise happens quite a bit and I have lost many a shot forgetting to disable IS (shooting the A1 or older models).

Interesting. My primary subject matter in this case being racecars, I often try to shoot as slow as I can manage to "preserve" motion but I still want the subject to be sharp hence I am trying to see how the tool helps. But I will keep this in mind. Thanks for the reply!
