[Excellent] Sigma 10-20mm f/4-5.6 EX DC HSM for Canon EF Mount.  Comes with Original Box and padded Sigma case, instruction manual, and Hoya 77mm HMC UV (C) Digital Slim Frame Multi-Coated Glass Filter that has been on the lens at all times.  Zero scratches or blemished on the lens glass.  Or filter for that matter.

I have two of these and selling one of them as I never use both at the same time.  Love the artistic shots I get with this lens!
