I bought the lens through the Refurb store last November. Used it for a few sporting events. AF accuracy was great both indoors (basketball) and outdoors (track & field, softball) with my 7D-II.
The lens is in the same condition as when I received it from Canon. No scratches on the tripod mount, no scratches or scuffs on the lens or hood. Optics are clean & clear. AF, IS all work as they should.
- The lens arrived with a small paint imperfection under the word "Ultrasonic". I've shown it in photo. It looks like a bubble but it is solid.
- You can feel a bit of mechanical action as you turn the zoom ring. If you focus on it you can feel it. If you just use the lens you never notice it.
- There are two very small pencil point sized marks in the paint along the edge near the mount.
