Item Description
I purchased this lens from a fellow PF member back in 2011 when I spotted it for sale. I was just starting out with photography and saw the great ratings on PF and found I wanted to have it.

This lens does have issues that need to be addressed, as it's rated Good for a reason. The glass is clean with minimal dust and there's some minor wear on the body of the lens due to the Sigma crinkle finish wearing off. The window above the focus scale has a small crack too.

The issues that this lens has, which were stated by the seller at the time of my purchase are as follows:

The good: This lens is in good mechanical and optical condition, and gives good pictures when it works.

The bad: When you mount the lens on the camera, 9 out of 10 times it gives you an "F--" or "A--" indicating it does not transmit the aperture correctly.

The previous seller sent it in for repair to fix the aperture issue, but Sigma had stopped making the PCB so the seller sold it as he had found a more reliable lens for his purposes.

Since the aperture does not function properly, I used the lens in M mode and set the aperture by hand, as this allowed me to work really easily with flash as this was the widest lens I had when I was starting out with my professional photography career. This lens produces fantastic images once you know about its quirks.

The lens comes with the original hood and non-original front and rear caps, with no case.

If you have any questions, please feel free to ask. The marks on the front of the lens were due to the poorly cleaned microfiber cloth I used to clean the lens prior to the photos.

Here's some of the product, event, and landscapes that the lens blessed me with over the years:
