A prime lens with a 24mm focal length and an aperture of f/2.8. This is a model from a generation without the "D" marking. There is some clouding around the center element. Please assume that there may be dust and mold inside, as this is an old lens. I believe it will not significantly affect shooting unless used in extreme environments. No returns or exchanges, please. - Model Name: AF NIKKOR 24mm f/2.8 - Aperture: f/2.8 - Focal Length: 24mm - Lens Type: Prime lens - Lens Diameter: Filter thread 52mm Thank you for looking.
