Re: Nope, it's rather the opposite.

I would think the cost/performance function is a curve, not a straight line.  Ie., a huge sensor is difficult to produce a lens for (due to massive moving parts), but a super tiny sensor is also difficult to produce a lens for (due to requirements on the optical precision).  It's not clear to me where the optimal spot on this curve is--it could be FF, but where's the data?

I would think the optimum would depend on the field of view.  I can see how a larger sensor is easier to design wide angle lenses for.  But not for telephoto lenses.  And the NEX system has the very short flange distance which should also make wide-angle lens design easier (probably makes no difference for telephoto lenses.)

These are great points. It would be really funny if the optimal spot on the sensor-size curve ended up being 4x5 or 8x10.
