I usually turn off IR for any critter tracking,

be sure to leave uv on.

So I made an obvious typo.

it's not the first time and certainly not the last.

as it slows down the
tracking a tad.

actually it doesn't, since stabilization is an independent system which
keeps the subject steady in the frame, making it *easier* for focus
tracking to work.

it takes time to stabilize.

the delay is only at the start.

after that, stabilization is continuous, improving both autofocus and
subject tracking.

This image would not be the same with
stabilization.

without a controlled comparison of photos taken with and without
stabilization, there's no way to know what differences there will be,
if any. for all you know, a stabilized version would be better.
