For repair a Sigma 150-600mm f5-6.3 DG for nikon.  With original box.  Lens works as a manual lens, thats about it.  Lens rolled off a counter top and stopped working, everything electronic on lens doesn't work.  Glass is still in great shape, with only a few minor dust specks.  Zoom is still smooth, focus ring is a bit grindy but does move feely.  Sold as is for repair or parts.
