Thank you for viewing this item. This is a CONTAX Carl Zeiss Planar 50mm F1.4 AEJ. There is some dust and debris inside the lens. There is a slight oil stain on the aperture blades. Neither of these issues affect image quality. It has been stored in a dehumidified storage box. A Fotodiox mount adapter for converting Y/C mount to Sony E-mount is included. Lens cap, lens protector, and C-PL filter are also included as extras. Although it is an old lens, it produces very sharp images. How about adding one to your collection for playing with old lenses? Please understand that this is a used item, and only purchase if you are comfortable with this.
