This Sigma 10-20 is in 100% immaculate, brand new condition. There are no marks, scuffs, scratches, etc of any kind anywhere.
It's very sharp, focuses quickly thanks to Sigma's famous HSM focusing mechanism and has never let me down. It takes amazing pictures and has the cool ultra-wide effect without the fisheye distortion.
I have kept a UV filter (not included) on it since the moment I took it out of the box.
It will come with the following:
Centre-pinch Sigma lens cap (the older models had the side pinch, which are impossible to remove once the hood is on)
Sigma rear cap
Sigma hood
Sigma padded bag
All documentation (blank warranty card, manual, etc)
2 years of warranty left
Asking $650
This is a great deal, Lens and Shutter sells it for $851 with tax.
