Some people like to look for nicknames for lenses, perhaps this would be a good and fitting nickname for the 10-22mm. Not sure about the turd part, but it sure is overpriced compared to the magnificent Tokina 11-16mm 2.8. When you charge more than your competitor, you should have a faster lens with a better build and better IQ. But the Canon loses in all 3 catagories. Go figure.
The canon blows the Tokina out at 10mm, and 17-22mm. Just saying
