Just bought a 120mm f/5.6 Jos Schneider Kreuznach Aerogon lens for my 8x10 view. Lens stops down to f/22, is quite heavy and the glass, as best I can describe, looks like a large verson of the Hologon lens (for 35mm format) or pictures I've seen of the Hypergon lens. Held the lens with flange in front of my 8x10's front standard and it easily appears to throw a sharp image across the ground glass. Hounting the Aerogon in a shutter, if it is even possible, would seen prohibitively expensive so I plan on using the Aerogon like my little barrel mounted Protar... stopped down the lenscap becomes the shutter.

Does anyone have any information or experience with this optic?
