Re: How would lens optics/engineering drive toward an optimal sensor/film size?

The related question I have is, if we started with some goals for the
glass and worked toward a sensor what kind of system would we end up
with?
The prior posts are mostly about sensors...is that because we are
sensor-centric or...what?
Is a 50mm 1.8 35mm lens a great lens optically, and for moderate cost,
because its in the sweet spot for the 'physics of glass' or is just
the most engineered / largest selling lens and market size reduced the
cost?
Still interested in physics of the "Normal Lens".
As a D50 owner, a fast 35mm lens will currently cost me 2x - 3x the cost
of a 1.8 50mm.
Will we see fast, good, cheap "Normal" lenses for the 1.5X format?
For wide angle for a given field of view, is a 24m easier to get
'good' (distortion, flair, etc) vs an 18mm lens? So body and sensor
wars aside, if we could start over and pick a format driven by optics
what would it be?
Same here, just a matter of time for good 18mm glass at 24mm prices...or no?
