I have some wide Nikons and a Tokina I want to sell or trade so I can get a long and fast 400mm or longer lens. The 14-24 is a brilliant lens for full-frame architectural and group photography - $1100 OBO. The 17-35 is just right for full-frame group portraits and close-in sports shots -$600 OBO. The Tokina is a DX that lets you get close to the action - $250 OBO.
