I am selling this lens because I am changing mounts. I purchased it new from an online shop in May 2025. I have used it outdoors about 4 or 5 times. When not in use, it was stored in a dry cabinet. There is a scratch on the side of the lens, but in my amateur opinion, there is no dust or debris inside the lens that would affect shooting. The operation is also problem-free. I will also include the lens filter that I have been using since I opened the box. The SIGMA 16-300mm F3.5-6.7 DC OS HSM lens is a high-performance zoom lens that covers from wide-angle to telephoto. - Model Name: 16-300mm F3.5-6.7 DC OS HSM - Brand: SIGMA - Included Accessories: Instruction manual, warranty, lens cap, lens hood - Condition: Like new - Focal Length: 16-300mm Thank you for looking.
