I have one of these, and was unaware of the potential issue until I read this post. I just checked my lens and found that it falls in the range you’ve listed. Although the EF-S 18-200 is out of my rotation now, I must have taken a couple thousand shots with it before I moved into the FF and L world. I’ve had no issues with the lens at all. While the EF-S 18-200 has its faults, versatility is not one of them.
