Hello, very interesting results you got with the lens. I'm going to have have a look around and find one for 4x5, at least, if not a 5x7 or 8x10. Regarding your need for a shutter for that lense.... I'm working on an idea... bought a junker 4x5 Speed Graphic... only thing working was shutter, so I cut off about an inch from the front of the body so that I only have left is the wback part with the shutter curtain and mechanism. You get a 6x8" box, but you have a light 4x5 shutter hole when wide open. Still haven't decided how to mount it on my 8x10 Deardorff. Anybody have any ideas, I'd like to hear about it.
