This lens is pristine. Been in a desk drawer for a hundred years or something like that. You never see them this clean! The shutter has the same function as a "Studio Shutter". Open and closed as fast as you can cycle, or open with T and leave it open. This one works with an air bulb. About 1/5th second is all it's going to give you. This is a classic lens that a home portraitist would use on 4X5. Don't look for weird swirliness with this one. Looking for $385.00 for this. I'll pay the shipping in USA.
