This is the Canon RF 100-400mm f/5.6-8 IS USM lens. I purchased it at the beginning of this year and have used it several times, but I am selling it due to equipment upgrades. I mainly used it for shooting trains and airplanes, and I didn't use it in any particularly harsh ways. After use, I always cleaned it and stored it in a dehumidified storage box, so I think it's in good condition for a used item. I can't see any dust inside the lens, so there are no problems with shooting. The exterior has some scratches that show signs of use, but I think it's not noticeable for most people. If you want any additional photos or information, please feel free to comment. *If you would like to purchase the lens hood, which is listed separately, at the same time, I will offer a discount and include it. Please let me know in the comments if you would like to do so.
