Olympus G. Zuiko Auto-W 28mm f/3.5 This is an interchangeable lens for the Olympus Pen F, a half-frame SLR camera. The lens is covered with what appears to be bubbles (photo ④). It is not suitable for shooting, so it is being sold as a junk item. The aperture and focus operations seem to be working fine, so how about using it for parts? The item is as shown in the images. Please consider the item based on the images. Thank you for looking.
