I have listed this super-telephoto lens on Ebay (item 330461118594) with no reserve!!!. It is an old lens. Well kept and no longer used. Almost in Mint condition. Case included. If anyone is looking for a lens for bird photography, but don't want to spend many thousand $USD, you may consider this one. It has a m42 mount so you have to use an adapter for Canon, Nikon, Sony, on Pentax DSLR.
Please see my other items on Ebay as well.
