This is a set of a Canon Lens 35mm F2.8 L39 mount + VM mount adapter. I purchased it used about a year ago and have been using it. I think I've used it less than 10 times. The lens is in very good condition, but there is a small amount of dust inside. There are no problems with the image quality, but please understand that this is a used item. The original caps are missing for both the front and rear. No returns or exchanges accepted.
