The Tamron A035TM tripod mount is compatible with 100-400mm and 50-400mm lenses, providing stable shooting. - Model: A035TM - Compatible lenses: 100-400mm F/4.5-6.3 Di VC USD, 50-400mm F/4.5-6.3 Di III VC VXD - Accessories: Screws, box Purchased in March 2025 from Map Camera for ¥12,375 (including tax)! I no longer need it because I sold my 50-400mm lens in August when I upgraded lenses. It's in beautiful condition with no noticeable scratches because it was used infrequently! It's useful for situations where you use a tripod, such as landscape or fireworks photography!
