Sorry, Mike.
I forget that sometimes I use motion picture lingo

Dutch angle refers tilting the camera at an oblique

I think you are confusing acceleration with velocity.
When panning, you should move in a way that is as constant as
possible, trying to minimize accelerations. So no, the orientation
sensor has no effect then.

Don't forget, too, that the normal panning motion is to
rotate the camera. An angular rotation (even at a constant
rate) *is* an acceleration, and will be detected as such

Fair enough.
The acceleration needed to confuse the sensor is bigger than that,
though. Besides, that vector would be along the lens
axis--perpendicular to the two directions the sensor detects.
The best way I found to confuse the sensor is to move the camera to

The SR shouldn't be moving at all when you rotate the camera: the magnets
keep it in place.

No, I can't hear or feel anything like that. I don't have a battery

It's not a rattle per se, just a slight amount of

difference. Camera on/off
I feel the same rattle. It's very subtle. It's not the battery or the

One second is way too much to ask for. Try shooting with a 50mm lens
at 1/15th second with the SR on and off. You should see a difference.

second is way too long to be effective with SR, it

huge vs. SR OFF(especially at .3 sec).
