SIGMA 17-70mm F2.8-4 DC MACRO OS HSM EF lens for Canon

The lens is new. Was purchased last week. Unfortunately, it doesn't fit my Canon 1D well. (the 1D has a APS-H sensor, slightly bigger than the APS-C sensor, as a result the image circle projected isn't big enough to cover the whole sensor and i get black edges/corners on pictures).

It will fit any Canon that has the EF port. This lens was released around March 2013.

I have taken about 20 pictures with it, there are no scratches, marks or anything on the lens. It is in new condition.

Comes with the box and everything that came with it.

It retails for about $540 - $560+ tax.

I am looking to get about $500 for it.
