Does anyone know the history of Componons that came in shutters? Were they intended for darkroom work; were they created from enlarger cells or were they sold as a finished product? I have an 80mm in shutter that I got years back for my 6x9, which I rarely shot, and while just cruising the cameraeccentric site I noticed that he has one for sale and he lists it as a macro, studio (product?), and landscape lens. I'm just trying to determine were it's strength lies.
