This is a genuine wide-angle G lens. I purchased it used, in almost new condition (used a few times), and used it for a year. Operation has been confirmed. I am selling it because I am changing equipment. I attached a lens filter immediately after purchase, so the front lens is very clean, in my amateur opinion! There is some slight wear around the zoom ring, aperture ring, and custom button. Also, the front cap, rear cap, and hood show some signs of use. Please check the condition in the photos and understand that this is a second-hand item before purchasing. [Included Items] Front & rear caps, lens hood Box - the barcode section has been cut out ~~~ Focal Length...20mm Maximum Aperture...1.8
