Re: Why do lenses need AF calibration?

I've read several threads about people who have sent their lenses back to Canon for calibration.

I laughed when I first read about this because I didn't know there was a way or a reason to calibrate a lens.

I'm one of the lucky people who have used Quality Canon lenses for several years and have never owned one, or even seen one, that needed to be calibrated.
