Please note: I will be away from March 29th to April 13th, so purchases made during that time will be shipped after April 13th. This is a Nikon F-mount AF-S Nikkor 28mm f/1.8G lens. I purchased it last year at Map Camera Shinjuku, but I've only used it once, so I'm selling it. There is absolutely no dust, mold, fogging, or balsam separation visible in natural light. The optics are in very good condition. Includes a hood. The front and rear caps are new, genuine products. Please feel free to ask any questions you may have.
