Choukorov and ican - look at the ebay history on this item. In all mounts these are selling for at least twice their initial price. When I was shopping this Feb. for this exact item, the prices were hovering around $1,800.00 to $2,000.00. In the aggregate, Ebay selling prices probably represent true market value plus the Ebay surcharge.
I will endorse this 125mm ApoLanthar as the most gorgeous 1:1 macro lens, and a pleasure to focus with its very long focus throw. Sharp, and lovely bokeh - great fun to shoot wide open as well as stopped down. Curiously, the center focus point confirmation on my 6D does not work with this lens, but the other 10 points are happy.
