I have a very nice Tamron 28-75 f/2.8 for Nikon mount that I'd like to sell to free up some funds. This is the older version without a built-in-motor. Focus is accurate on my D600 without any adjustments. There are 2 specks of dust inside as seen in the pics below but I have never had them show up in any of my photos. Comes with box (missing bar code), both caps, and hood. Also included is a brand new Sigma DG 67mm Ultra-low reflection multi-coating UV filter.
