In the case of the Leitz 35mm format lenses we're talking about high end *consumer* (well, OK, and professional) grade lenses, which use designs susceptible to mass production (albeit on a small scale). These are a *VERY* long way down the scale from the optical designs which are used in 'money is no object' applications like surveillance satellite & aircraft optics, and the optical systems used in some military applications. However few people without security clearance ever get to hear about the state of the art. dmorton@cix.compulink.co.uk | "The loss of an old man david@cassandra.compulink.co.uk | is like the destruction Kilburn, London, England. | of a library"
