TAMRON ADAPTALL-2 single-focus lens, 28mm F2.5. It has an N/AI (Nikon F mount system) Adaptall 2 mount. A Kenko MC SKYLIGHT [1B] 49mm filter is attached to the front. Due to the age of the lens, there are scratches, small marks, and dirt on the exterior. Please assume that there is also dust and slight clouding inside the lens, commensurate with its age. We have not performed professional disassembly, cleaning, or detailed checks. As there is no camera body, we have not been able to confirm the operation of focusing, aperture, or actual shooting, so we are selling it as a junk item with unconfirmed operation. Please understand that we cannot provide any warranty or accept returns for any defects, including image quality issues, focusing problems, or aperture blade malfunctions. [Included Items] ・Kenko MC SKYLIGHT [1B] 49mm filter *All other included items are shown in the photos. We will carefully wrap it in bubble wrap and ship it in a box. Please purchase only if you understand that this is a used and junk item.
