The NIKKOR 50mm f/1.8 lens offers high descriptive power with a wide aperture range. It's a pancake lens from Nikon. There appears to be slight haze and what looks like mold inside. It's minor, so I don't think it will significantly affect the photos. Please comment if you have any questions or would like additional photos. This is an old product, so please refrain from bidding if you are looking for perfection. Basically, no returns or refunds, please. - Model: NIKKOR 50mm f/1.8 - Aperture: f/22 - f/1.8 - Lens Diameter: Approximately 50mm Thank you for looking.
