FYI you should know that some Canon lens do not require IS to be turned off when on a tripod.
But you still turn it off (if you want good results)!!!!!

Next time you see that guy, take a picture of his gadget so we know what it is. Digital pictures are free (once you get past the capital cost).

When I say drift, I mean I am locked on to a subject...and then the camera moves slightly. I am using a gimbal Sirui head on a Manfrotto tripod 055x PROB. Some of the Park photographers say Stabilizer on others say off. I did use a shutter release and none of them liked that. Maybe I need something heavier????

Well, it looks like the OP has fled the scene!
I find it amazing how much misinformation has been put forth on this post about tripods and IS, VR etc. Some of it is old info that is no longer true or is only partially true. Much information is stated as fact when it is not.
For those of you who want the correct information about image stabilization for Canon Lenses go to this web site: http://cpn.canon-europe.com/content/education/infobank/lenses/image_stabilisation.do
It is from Canon/Europe and is their official "Canon Professional Network" site. There is no North American counterpart.
In it you will find that of the 30 lenses listed only 7 are not "Tripod Aware" and you will see that those 7 are older designs, some of which have been upgraded like the 100-400 mm IS II.
You will see that Canon actually recommends using IS with a tripod under certain situations with very long lenses.
I believe the OP was seeing a phenomenon that I have observed with my canon 7D Mk I and Canon 500mm f/4L, when mounted on a tripod, with IS on, the image will "drift", that is move slowly, around the viewfinder. This is especially apparent when I use the 1.4 or 2.0 Teleconverter and am trying to focus manually using live view. With IS turned off, the image bounces around so much when I touch the lens focus ring, it is nearly impossible to see well enough to focus. Zoom in to 5x or 10x and you multiply the effect. If I turn on IS, the image stabilizes, enabling me to manually focus.
Has no one else observed this phenomenon?

Sorry, I thought you had given up! Glad you are back.
A camera on a gimbal head should not move, even if the clamp is not tight, as long as the camera/lens is balanced. You may need to move it forward or backward on the mount to achieve this. Once both the pivot and the pan knobs are tight, there should be no movement. Is your head to tripod connection good and tight? What lens are you using? Does it have a trifold foot? A picture of your rig might help.

Gene, the point is and was that he made an untrue statement that it should always be turned off. Some Canon lens do not require you to turn it off.While this may be true, there is no free lunch. IS... (show quote)

Smith934...what would you recommend?
Since I shoot Nikon I'd obviously turn it off, but my mention was of "some" Canon lens.

I'm so sorry if stating fact is considered being "argumentative". Please don't make blanket statements that are not true of all lens.Please dont confuse people by being argumentative. The IS feature should be turned off when mounting a camera on a tripod in 99.99999999999 percent of the time.
