Nikon AF-S NIKKOR 17-35mm f/2.8 D IF ED Included: Front cap, rear cap Filter Condition: Used with a D300 until six months ago, and my family says that both the zoom and AF functioned smoothly. They mentioned that there was occasionally some AF noise. I shone a light through it while taking photos, but I don't see any mold or haze. Please forgive me, as I am not a professional. Since I don't have a camera to check it with, please make your judgment based on the current condition.
