I think you mean the iris as the shutter is part of the camera, not the lens...Was the lens dropped or banged up against something?...I like my old manual focus macro lenses, they can take a beating & still work fine...Hope it's not an expensive fix...

Thanks for the advice guys, but I cleaned the contacts and checked it out on two different bodies, Auto focus works just fine, but if I shoot at anything other than f/2.8 there is no capture only an error statement, the shutter is definitely stuck. I was getting very different lighting results in consecutive shots the day before, I thought that it was the flash causing that, now I suspect that it was the shutter's improper function.
