I had the same issue with my 30D. I tried it once and didn't like the results at all. It was better with my 40D (a little better AF in that camera) but I have no issues with it at all on my IIN. Can hardly tell the difference with or without.
Now if I would just gt my 120-300 back and have it actually focus I would be a totally happy camper.

Thanks, that is nice to know. I borrowed a friends 1d Mark II to use at my son's football game today. We will see how it goes.
