To make a long story short....


Called Henry's, asked for my lens back due to the current lens issues, offered3 choices...


1. Exchange for new lens - lack of confidence on my part


2. Exchange for the original


3. Refund


Took option 2 and the capabilities of said lens is night and day compared to the second unit. No focus hunting -aim, lock and shoot!


peety3 was right, I will just hang on to this lens until something really bad happens which I can live with...


Curious...could therepossibly bea QA issue with Canon with this new lens?!?!?


Thanks for the responses/suggestions....
