Thank you for viewing. This is a Contax Carl Zeiss Sonnar 2.8/180 MMJ. It is a C/Y mount. [Appearance] It is in very good condition with almost no scratches or scuffs, and no whitening of the rubber. I have used a flash to make any scratches noticeable, but there is no whitening of the rubber. *Please refer to the photos. [Optics] Visual inspection shows no mold, fogging, or balsam separation, and it is very clear. When illuminated with a strong LED light, there are a few extremely thin scratches and what appear to be traces of mold removal on the rear element, but these do not affect the image quality. Even when illuminated with an LED, there appears to be no mold, fogging, or balsam separation. *Because this lens costs over 10,000 yen, I have carefully checked it, but it is a vintage lens, so please purchase it if you understand that it is a used item. [Operation] Both the focus ring and the aperture ring move smoothly. The aperture blades also move smoothly and are functioning properly. There is no oil stain. [Included Accessories] ・Lens caps (front and rear) [Shipping] Shipping will be handled by Sagawa Express's valuable items service, and a tracking number will be provided after shipment.
