This is a beautiful Canon EF 135mm f/2L USM lens. I purchased it new from Camera no Kitamura and used it with care, but due to the focal length, I didn't use it very often, so it has few scratches and is in excellent condition, with no operational issues. This is one of Canon's legendary lenses, and the image quality is top-notch. There is no noticeable mold or dust inside the lens, but please refrain from purchasing if you are overly concerned about such things. No claims and no returns accepted. I am not offering discounts because there are many people on Mercari who make unreasonable and selfish price negotiations.
