Honest question. I don't get why a well made lens with half dozen machine ground lenses of a particular shape and in one configuration can cost 10-20x what another well made lens with a half dozen machine ground lenses of a similar shape and configuration? How can the shape of a lens element or the coating cost so much more to produce? What is special about this lens that Canon, Nikon or Sigma could not reverse engineer (i.e. lens shape) and produce for $400?
An interesting read from Lloyd Chambers here.
