Re: EFS 17-55 USM corner blurriness: experts' opinion needed !

I tried factory service for just 1 lens and problem was switched from top to bottom. Others have been returned for exchanges. However, I do resent being the QC center for a $500+ lens. With the high precision computer controlled manufacturing and testing equipment available today, this shouldn't be an issue.
