Sigma APO 135-400mm F/4.5-5.6 Telephoto AF Zoom Lens

I am not a camera lens expert. I own a 2nd hand store and resell things. Please refer to ALL pictures for the most accurate description. I have not tested this lens; it seems to adjust/move very smoothly. The lens does show some dust & what must be some mold…I think you should be able to get a very good idea from viewing all of the pictures (especially pics #18 & #19). Also, there is a scratch on the lens that I have circled in picture #14. There could be other very minor scratches that I may have missed. Comes with case and box (the box shows a lot of wear; as pictured).

Please ask any questions BEFORE buying and I will do my best to answer them!
