The important thing to remember when it comes to IS/OS/VR is that it is
there to provide a fix for camera shake, not subject movement, and once you have
a shutter speed over 1/500 sec IS/OS/VR is irrelevant as the high shutter
speed should freeze all subject movement. Since you shot those ducks at 1/2000
you could probably have managed without IS.

I usually turn off IR for any critter tracking,

be sure to leave uv on.

UV?

You're slipping...
