You can choose faster and more expensive shipping during checkout. Please read full description, lens has issues with fungus. Please no returns on this item. Lens has been used, but it looks very nice. Unfortunately lens has fungus inside the glass elements. I see maybe 40-50% or half of one of the rear elements covered in fungus. So lens needs cleaning, or could be used for parts. Fungus might affect image quality. Other then fungus lens looks and works good. Filter rim looks good and it accepts filters. Glass does not have any large, noticeable scratches. Lens produces very sharp and nice images. Performance: Lens focus works well. Aperture blades are free of oil. Aperture is snappy.
