The point is...
If the APS size sensor gives acceptable performance, then a 24x36
mm sensor designed to the same pixel density and pixel performance
IS better. At any rate, the comment regarding medium format sensors
is still valid. Again, think about it.
This is true presuming that the ray trace from the lens to sensor
does not change dramatically such that the edge/corner areas on the
larger sensor are too oblique, or if the sensor has been designed to
be more tolerant of accepting light at oblique angles.
Ideally, a larger lens mount and lenses designed for a more
telecentric ray trace should be used. Less ideally, but still an
improvement, would be reformulated lenses with the same principle in
mind.
The secondary question is whether the larger sensor technology is
necessary. That's a qualitative judgement and I'll leave that for
others to debate.
