Like the x10 zooms that are popping up everywhere. Or the super wide zooms that are even super wide even on the tele end. We've come a long way since the first zooms. Like that early Nikkor 45-85, or whatever that was. I had one. Very forgettable. Took 10 years before I considered using another zoom.

I can see a number of parallels in the application of computers to lens design, as expressed in this paper, and the similar application to fluid flows and supersonic aerodynamics. In one case light rays are being traced, in the other the lines represent compression and expansion paths in fluid systems. One of my sons is heavily involved in what is today known a Computational Fluid Dynamics (CFD), where the process is applied to a wide range of engineering problems. Jim Nichols Tullahoma, TN USA
