This lens was recently tested (by B&H Photo) and is working, but there is some condensation/fog that has developed internally (it appears to be on only one element). The photo of Chuckie is a test shot through this lens. The front and rear glass are clean and have no scratches.If you have the time and skill to clean/repair this, it should be a great addition to your kit! I attempted to photograph the interior glass with my phones camera to show the fog. The item "SIGMA APO 300 mm F 2.8 For Nikon For Parts/Repair" is in sale since Wednesday, July 10, 2019.
