For sale to organize my lenses. I purchased this as a used item (almost unused) and used it only once. There is a chip on the lens hood attachment, but there is no problem attaching the lens hood. Also, there are no scratches or scuffs on the lens itself, so there is no problem with the image quality. Please understand that this is a used item before purchasing.
