This is a Nikon Nikkor UD Auto 20mm F3.5 lens. I purchased it in February 2025 from Fujiya Camera in Nakano, Tokyo, to photograph a room. According to the receipt, the lens was cleaned before being put on display. There are mentions of dust and minor dirt, but I couldn't see them. I only used it for one day. I used it indoors to photograph a room, attaching it to my Zf via a mount adapter. After that, it was stored in a dehumidified storage unit in my study. The focusing ring feels smooth and nice. Included are the receipt from the purchase and the front and rear caps. The caps are not the original ones from that time period, but from a later era, so please consider them as a bonus for lens protection.
