Got this shutter and Wray 5 inch "Special Copying f4" lens a while back off of a huge process camera used to fabricate custom matrix plates for one-off microprocessors just before they bulldozed the building. Man I left a LOT of stuff behind but, you know you can only take so much... Being that I have started down the ULF slippery slope, I eyed the combo and wondered the inevitable, are they useful? (Note that the shutter was at the end of a large, metal cone and the lens was mounted on a plate at the other end of the cone, not that the lens was mounted ON the shutter...) I would imagine the Ilex shutter would be useful if I could find a lens to fit it, but the Wray lens is quite heavy and large. Just how do you figure the coverage circle of a lens? What useful lenses fit the No. 4 Ilex shutter, assuming 8x10 or similar film size. As always, thanks for the advice and sorry for the crappy webcam pic. EDIT: Hey I just noticed this crazy shutter has a aperture in it behind the shutter blades!
