The Nikon Noct 58mm f/1.2 from 1997 is famous for having excellent coma control wide open. Sources generally credit this to its being one of the first lenses that used an aspherical element, which had to be hand-ground at the time (making it very expensive). Comparisons to recent lenses still show that it has better center sharpness wide open and less coma.
But aspherical lenses can apparently be produced very cheaply now. Even Nikon's 35mm f/1.8 has an aspherical element, and it's just about their cheapest modern lens at $200. Is there any reason that the same cheap aspherical lens manufacturing techniques could not be used to produce the same design that had to be hand-ground in 1997? Did the Noct's aspherical element use such an exotic shape that it still could not be made with a machine today? I assume there must be a technical reason that such lenses are not produced because there's a huge market of astrophotographers that want large apertures and low coma.
