I had a Sigma telephoto lens for my Nikon D600. I took it to Mexico to photograph my son's wedding near the ocean. In the process of taking photos of the surf, a rogue wave came in and hit my camera bag and soaked the lens. I sent it back to Sigma and the word came back that the lens was not worth repairing. They then asked if I wanted the lens returned or should they scrap it. It would cost $10 to return. Is there any reason for me to get that lens back?
