You shouldn''t have any problems at 1/1000 unless you had 8 cups of coffee just prior. I have had good shots at considerably slower shutter speeds. Two things - learning how to handle such a big lens takes a couple of outings, so give yourself time to get used to it. Also, make sure you MFA the lens. You've spent enough, now it's time to make sure you wring every bit of performance from it.
. Getting a sidekick soon. So my shots seemed to be a bit blurry even on shutter speed of 1/1000 with birds in flight! Wow I had no idea the amount of work action shots can be! I loved it! Got my butt kicked but kinda expected.
