Genuine tripod mount specifically for the Tamron telephoto zoom lens "100-400mm F/4.5-6.3 Di VC USD (Model A035)". I am selling this because I purchased a lens from another manufacturer. There are no scratches from a layman's perspective, but please refrain from purchasing if you are overly concerned about this. Due to the prevention of product substitution, returns and refunds are not possible. Thank you for viewing the product. This item is also being sold on Yahoo Auctions, and will be discontinued when sold out. We apologize for the inconvenience, but please confirm availability before purchasing.
