I suspect that Nikon has Monte Carlo style simulations that work to design lenses. So what this really may mean is that lens design will become a little cheaper.

That's cool. I wonder what the practical effect will be?

And it looks like they used an image of a Z camera for the illustration!

Yes, it seems so for a while at least.

Here is a look at how that equation translates in an actual glass design:

Talk about asphericals, will be interesting to see how it can be made in real glass...

Cheap lenses, other than kit glass (18-55mm VR) have been dead for the last 5 years, nothing new to see here.
