This is a super wide-angle zoom lens from SIGMA. * Kenko lens protector is not included. Includes the SIGMA lens hood, lens storage case, and original box. Purchased new in June 2019 and used several times, but I am selling it because I changed mounts in January 2021. The main lens is undamaged because a protector was always attached. There have been no drops. I used it with a Nikon D5200.
