Notes

This copy has a flaw in the front grouping of glass. Shipping pressure caused a bit of glass to break away from the edge of the rear most element of the front group. The fragments have been removed from the inside of the lens. We see this issue quite often, and it does not seem to get any worse under normal use. Please be aware that it is highly unlikely that this will effect image quality.

Comes with hood, caps, tripod ring, and original Sigma case.
