I am selling this because I no longer use the EF mount. All functions are normal, and autofocus is not a problem. A 72mm to 82mm step-up ring is currently attached, but it can be removed. I will include it as a bonus to accommodate more filters. The lens cap is a Sigma 82mm (front), and the rear cap is Canon. The original 72mm cap is not included. Both the front and rear elements are free of scratches and dirt, and the optics are very clear. *As this is a used item, there may be some signs of use or dirt on the exterior, but this does not affect shooting in any way.
