Most studio films were still shot in B&W, and virtually all the indie films were. Obviously, the lower the budget, the more likely there will be poor glass, but in reality, I find most fifties film look pretty crisp. Prolly because they dumped a huge amount of light onto those stages.
I wonder how the Technicolor CineStyle would hold up if you turned the color off entirely for B&W (I'm a big proponent of shooting in B&W instead of just doing it in post as it will "color" the entire production design when you're going for the contracts between black and white...i.e. you might pick a color for costume or prop that would look goofy in color but looks great in B&W).
