I was recently out shooting at a different area of my home airport, one that required shooting through a fence.
Basically, I was pressing the lens (hood) up against an opening in the fence and shooting away, with the IS on. My questions are:
1) I know that, for example, when using a tripod the IS must be turned off otherwise I risk damage to the lens. Is pressing the camera up against the fence similar to using a tripod in the sense that I risk damage to the lens? Should I turn the IS off when shooting through a fence?
2) While shooting through the fence, I noticed that pretty much all of my shots, taken at the long end of the zoom, exhibit sort of an out of focus or blurry characteristic. I wonder, could this have been caused by #1 above? Perhaps leaning the lens up against the fence threw the IS "out of whack" resulting in these poor images?

I don't have knowledge on whether the IS causes your blurriness (sounds unlikely though), but I have shot through fences with the 100-400 on a tripod ( IS on ) and still got decent results, so go figure

Quoting AC888YOW (Thread starter): when using a tripod the IS must be turned off otherwise I risk damage to the lens.
I was under the impression that you have to turn the IS off not because it might damage the lens but because vibrations from the IS mechanism itself could set up a feedback loop, causing the picture to move erratically. I doubt whether the same thing could happen when the camera is handheld, even though you might be partially resting it on a fence.

The out of focus or blurry charateristic is the fence. If you do not shoot exactly through the middlle the fence will be in the shot. Because you are shooting throuhg the fence they will only be very feint but they are there.
