I have a Sigma 70mm EX-DG f/2.8 Macro for Nikon mount, sitting here on a shelf in the original box with case and paperwork for sale.
It's a fantastic lens, absolutely nothing wrong with it and no damage, less than 8 months old with about 100 shots taken on it. I don't have a Nikon body at the moment, so I simply don't need it and would rather sell it than watch it gather dust.
I think they go for about $375 brand new, I'll let this one go for $290 plus shipping.
