Mark - It was a problem specific to some copies of the lens sold about three years ago and I'm not sure where I read discussions about it -- probably on Rob Galbraith forums. I was shooting a soccer match one day when it first happened to me -- got an error code 99 as I recall. Nothing worked and I had to turn the camera off, remove the lens, replace it and then turn the camera back on before I could shoot again. Later I read on a forum somewhere that some copies of the lens had the problem and this was the only fix that worked. It really got to be PITA with mine and the fix not only took a bit of time but also exposed the sensor to dust. At a game one night I asked a PJ friend if he had heard of the problem and he was well aware of it -- seemed to be common at the time. I got so tired of it happening to me that I seldom use IS on that lens any more and never to shoot action sports unless I'm prepared to go through the fix when it locks up.
If you shoot with IS on all the time you probably have a good copy and there's nothing to worry about.
Jerry, Now that I read this, I realize that I do get lockups, but I never attributed it to the IS of the lens. I probably have my lens two to three years also.
I've never taken the lens off the camera, though, to solve the lockup. I simply remove the battery quickly and shove it back in. This solves the problem every time. I've also experienced the lockup when carrying the camera by the lens. In fact, it's either been as a result of that, slung over shoulder on a monopod attached to the lens, or from pressing the display button when the camera is busy writing.
All in all, battery removal always solves the lockup. I've never removed the lens to cure it. Just a thought.
