i know im not matt, but i do know a bit about light and lenses and such. A good lens is made from better glass, which will have a lower, more linear diffraction index (the same reason a prism splits light, but its not what you want in a lens), even toward the edges of the lens. (or they play some tricks with the light and use lenses to cancel out the diffraction. A lower diffraction index will produce better colors, and a sharper image. a more linear index will make sure that the colors (roygbiv) all appear more realistically. Also, the machining processes in high quality lenses are much more precise (micron tolerances) to the point where a really high quality lens will have almost perfectly parallel wavefronts of light (which is what you want). as to the flattening, that happens with high levels of zoom. why it does that is not something i specialize in, so i hope someone else will chime in, but i hope that helped with your lens question.
