some specs

What is exactly wrong with the aperture in your lens; are parts really broken or 'only' misaligned?
Thanks for this: I love the ad!

The blades are misaligned and several are badly bent. Three are out of their sockets. I guess it could be all straightened out by a competent repairer. I donít see how to disassemble the section with the aperture mechanism or I might have had a go myself, no doubt further complicating the situation. The glass is pristine.
Unless the aperture is either fixed or removed there is no way to use the lens unfortunately.
