Please: READ LENS INSTRUCTIONS!

Canon 70-200mm f/2.8L IS II, user-manual quote (section:tips on using the image stabilizer):
"Using a tripod also stabilizes the image. However, depending on the kind of tripod and shooting conditions, sometimes it may be better to turn off the Image Stabilizer function".
So I do not know what all the talk is about IS lenses after 1999?











BTW I own the lens. (so this is not idle talk)
I do know that I used the lens this weekend on a tripod to shoot bracketed HDR images with slow shutter speeds.
1.4 sec to 4 sec. (approx).
My subject matter was stationary.
I used a carbon fiber tripod (Feisol) with extra weight support hanging on the hook.
I used manual focus and live view on a 5DIII. (SOOOOOOOO much faster than mirror lock up)
All of the images were AMAZINGLY sharp. (ESPECIALLY for a zoom lens..damn, Canon got this one right!)
Why wonder. Use good practical technique. Why would I turn on image stabilization in this shooting situation? Do I need any gyros running? Do I need them turning on or turning off or any of that? Do I need to wonder if gyros might be turning on or turning off? Is there any reason that they would benefit this shooting situation. NO. By Canons own admission in the user manual...its pot luck. When I get up at 5:00 AM and go set up before the sun to take some photos...I do not want pot luck.
