Thank you for viewing. This is the Nikon Ai-s NIKKOR 50mm F1.8 (commonly known as the pancake lens), a legendary Nikon lens. It's incredibly compact and lightweight, yet its bright F1.8 aperture allows for beautiful bokeh and sharp images, making it a popular vintage lens. It's perfect for film camera users, and can also be used with digital SLRs and mirrorless cameras via an adapter. I am not very knowledgeable about cameras, so I am selling this as a junk item. Product Condition: Appearance: There are minor scratches and scuffs from use, but no significant damage. Please check the photos. Optics: There is some minor dust and debris inside the lens. Operation: The focus ring and aperture blades have been tested and are working smoothly. Included Accessories: Everything shown in the photos (front and rear caps, etc.). I haven't confirmed its shooting performance, but I believe it's a good item that has been stored in a warehouse for many years. Size: Nikon F mount
