Selling a Canon EF mount 24-105. I have a duplicate copy of this lens and need to let one go. The 24-105 f/4 is one of my favorite work horse lenses. You can go wide to telephoto and maintain a constant aperture. There are some cosmetic flaws from use, but structurally the lens and glass are in perfect working order with no scratches. I paid $800 for this a year ago here on gear focus. Let me know if you have any questions. Thanks
