I currently have a Schneider 100mm/5.6 Componon-S for my 6x6 and 6x4.5 work. I'm looking at getting an 80mm for larger enlargements. My first thought was to just get the 80mm/5.6 Componon-S, but I took a look a some of the Rodenstock lenses, and while more expensive got great reviews. So now I'm wondering if I'm missing anything. Much difference between the Compnon-S and the Rodenstock enlarging lenses?
