Thank you for viewing. This is a Nikon AI AF Nikkor 24mm f/2.8D lens. I purchased it used about 5 years ago and used it for a while, but I've been using Z-mount cameras more often, and I rarely use F-mount anymore, so I'm selling it. I have confirmed that it works properly. Included are the lens, lens hood, protective filter, and front and rear caps. Please understand that this is a used item.
