OLYMPUS M.ZUIKO DIGITAL 17mm f/2.8 wide-angle lens, compatible with Micro Four Thirds mount. - Brand: OLYMPUS - Model Name: M.ZUIKO DIGITAL 17mm f/2.8 - Lens Type: Wide-angle lens - Mount Type: Micro Four Thirds - Included Accessories: Lens cap I purchased this on Mercari around May of last year for about 11,000 yen. I'm selling this because I bought a new lens. I don't think there are any noticeable scratches or stains, but please refrain from purchasing if you are sensitive to such things. It works properly. Thank you for looking.
