Tamron SP 500/8. This is a fixed-aperture mirror lens. By purchasing a separate mount, it can be attached to cameras from various manufacturers. I purchased this as a store-exclusive item from Fujiya Camera in Nakano, Tokyo in July 2025. I only used it once, during a trip to Hokkaido in July. This is a rare early model. Many people are looking for the early model because the tripod mount was removed in the later models. The purchase rank was B-rank, and it was noted that there were minor scratches on the sub-mirror, but I couldn't see them. I think it's in good condition considering its age. It's been about 40 days since the purchase, so I don't think the condition has changed since then. Included are the hood, caps, an aftermarket PENTAX mount, and the warranty from the time of purchase. The warranty period remains, but it will probably be void after the transfer of ownership.
