does anybody know what the difference is between the two lines of schneiders and what the quality difference is?
The smaller lens is a Xenon, which is a basic Gauss design. The design is similar to the Schneider 50mm & most 50mm f/2 or so designs.
The larger is a Cinegon, which is a retro-focus or reverse-telephoto design. It has a negative section at the front, which reduces the focal length of a longer lens section, which allows more space in the rear.
Zeiss Distagons are retro-focus designs. The Xenon design would be similar to the Zeiss Planar design.
The Cinegon ought to have less light fall off in the corners than the Xenon.
The Xenon is an older design, but it's probably slightly contrastier since it has fewer elements & is set deeper in the mount giving it more of a lens shade.
I've never had a chance to compare the two for sharpness.

Leo and Max seem to know the most about them. Lotsa' folks here have had experience with them since so many have had their hands on a IIC, whether they'll admit it or not.
