Instant purchase welcome. I purchased this product used and used it with an EOS Kiss X5 and an EOS M2. I have no way to test if it is fully functional. Junk. I liked this zoom lens because it is moderately bright, lightweight, and can be used in a wide range of scenes, but I haven't used it much recently, so I'm selling it. It has been stored at home, so there is some dust and minor dirt. It's a standard, versatile zoom lens that's moderately bright, can focus closely, and can zoom, so I think it's not a bad idea to have one. The lens itself is also lightweight, so it's a great match for lightweight mirrorless cameras like the EOS M. I think it can be used as a main lens as well as a sub-lens.
