I purchased this lens a few years ago, but I've only used it a few times for things like photographing flowers, so it's in very good condition. The exterior has no scratches at all, and there's no dust, debris, or mold! It's one of the lenses I'd really like to keep, but I've decided to sell it urgently. It's definitely a great lens, so I hope someone who will take good care of it will buy it! Thank you.
