Asanuma Auto-Tele 400mm F/6.3 Minolta MD Mount Telephoto Lens

This Asanuma Auto-Tele 400mm F/6.3 telephoto lens for Minolta MD mount cameras combines vintage craftsmanship with long-range reach. It has that classic rendering vintage shooters appreciate—smooth contrast, natural color, and a bit of character that gives images a timeless look. Great for wildlife, outdoor, or distant landscape photography, it’s a solid manual-focus lens with a traditional all-metal build and comfortable handling.

The lens is in good working condition, and all functions operate as they should. Focusing is smooth, and the aperture opens and closes properly. The glass is clean overall, but there’s a small imperfection behind the front element—something that looks like minor internal spotting or residue that couldn’t be fully cleaned. It doesn’t appear to affect image quality, but it’s noted here for accuracy. A rear lens cap is included (not shown in the photos). A filter is also included, though it has some surface scratches and is being provided mainly to help protect the lens during shipping (shown in the photos). There is a short video clip showing the built in lens hood in operation. The final images in this listing were taken with this lens at F/8 to show its real-world performance.

Asanuma was a respected Japanese photographic brand active during the 1960s and 1970s, known for distributing quality optics produced by several top camera manufacturers of the era.
