my K35/3.5 is nearly magical...
I am not an optical designer, but like other engineering challenges I wonder if it is a game of compromises. Perhaps designing for maximum speed requires a compromise in other things, like color rendering perhaps. The K35 f/3.5 has a more simple optical design than many other lenses of the modern era, but sometimes simpler is better. Just thinking out loud, don't really know much about it.
