OLYMPUS M.ZUIKO DIGITAL 17mm f/2.8 Pancake Lens Thank you for viewing. This is a used item purchased on Yahoo Auctions. I am selling it because I purchased a 17mm f/1.8 lens. I dropped it when changing lenses, and there are scratches on the exterior. Please check the images. Although there are no problems with the operation or the images it takes, there may be some unnoticed effects. Therefore, it is treated as junk. To the untrained eye, there appears to be no mold or cloudiness.
