Now that "hybrid aspheres" are avail, where's the cheap "NoctNikkors?"

Could it BE that the PLASTIC part of the lens cannot be made
accurately enough (certainly not as well as a glass part) and thus
they can't produce a modern Noct?
Kind of reminds me of the plastic used in camera bodies "engineering
plastic," a new euphemism for the same old crap.

I guess you never fly on MD-80's, 737-400's (and later), 747-400's (and
later), 757's, 767's, Airbus 320, 330 and 340.

As to the upcoming 787, it takes the cake in composites and plastics and
the competing A-350 will go almost as far. The A-380 also depends
highly on plastics and composites to keep its weight down.

Darned engineers.

Imagine if a car could be made of mainly composites at a reasonable
price. (And price is the only barrier). It would be so much lighter
that an engine half the size or less could be used for the same
performance and safety. Then being so much lighter, the wheels could be
lighter, the brakes lighter, transmission lighter and so on. That would
save a hell of a lot of fuel and make a serial hybrid a very attractive
machine.

By the way Rich, enclosing the term _engineering plastic_ in quotes does
not work to make something non-genuine.

The brief descriptions of engineering plastic and commodity plastic on
Wikipedia is useful for your guidance.
