Just bought one and put it on my new xti. I am rather a newbie with the equipment, but it doesn't seem to stabilize the way I imagined it would. Stabilization is on and I am using autofocus. I am using it in rather low light, perhaps this is the issue?

Thoughts are appreciated.

there should be a rather visible difference, try turning the IS off and moving the camera from side to side, then turn the IS on and do the same, you should see a difference.

Make sure focus is half-clicked, also it is more noticeable at the longer end of it (135)

What shutter speed? IS allows you to hand hold a shot that is about 2 stops slower than you would normally.

For example: At the long end (135) the normal hand held shutter speed is around 1/250. So, with IS on you may be able to shoot hand held at 1/60. Anything slower and you'll probably see movement in the image.

First, this is what I like about this site. Everyone is very willing to help. Thanks for all the input. Headed to get my camera and do some tests based on the input. Thanks.

Thanks for the assist. I think I have it figured out now. I was shooting in low light and the shutter speed played a part.
