SIGMA 17-50mm F2.8 standard zoom lens for PENTAX K-mount. Includes a lens protection filter from Map Camera. It has been stored in a dehumidified storage, so there is no mold inside the lens barrel, but there may be some minor dust particles due to use. There are no particular issues during shooting, and I believe the optical performance is fine. The lens hood can be attached, but it rotates due to wear on the attachment part and cannot be locked. It can be used by holding it in place, and I used masking tape to increase the resistance of the locking part. Please check the details in the photos. This is just a casual inspection, so please refrain from purchasing if you are sensitive to such things. Thank you.
