I got out m camera system and was doing some small scale studio stuff I went tooverride the auto focus of the 28-135 so I grabbed the focusing ring and if wouldn't turn. No matter how hard I tried, then pop! and it turned. I was afraid that my autofocus was now only a manual focus lens but it still is an autofocus, It works good. On my recent trip to Ny, NY I noticed the IS was starting to shake some times but I haven't noticed it again. So I haven't worried about it, The IS has been working perfectly with that one occasion. I live in Texas and have noticed that some times when I'm shooting on hot days the IS acts weird. It was around 90 to 100 in Ny, when I was there.

I was wanting to know if anyone has had this trouble before?

My 28-135 goes funny too at times. I can feel a BUZZ and I presume it's the IS having a fit.

It doesn't do it often but when it does, it will do it several times.

If I take a picture during the buzzing I know it'll be blurred.

Haven't had that problem with mine, but all of a sudden lately it tends to "hunt" - especially when I am photographing courthouses & there is a flag pole or some other object in front of the courthouse. it does it on both my 300D & my EOS-3. I then switch over to Manual focus & that seems to solve the problem. I don't have this problem with my 20-35.

Is it windy?

When the front of this lens becomes loose, especially with the large Canon hood attached, the focus change slighly when caught by the wind and the camera try to re-adjust for that...
