Carl Zeiss Touit 50mm F2.8 X-mount. I haven't used it much because I sold my camera shortly after purchasing it. Dust inevitably appears in the product images, but there are no scratches, and it's practically new. Includes the original hood, caps, and a separately sold original UV filter. The filter was attached immediately after purchase, and it has been stored in a dehumidified storage. The 7th image is a photo without the filter.
