SONY genuine lens, FE 28-70mm F3.5-5.6 OSS. A KENKO Black Mist Protector is also included as a bonus. The filter is almost unused and very clean. Although there is a slight feeling of use, it is in very clean condition overall. It is a fully functional, beautiful item. I think you will be able to use it for a long time to come. The optics are as clean as new, with no mold, fogging, or dust.
