1) Why are camera sensors not square? Surely a square sensor is the most efficient way to get the best out of a lens?

2) Does using a Polarising filter reduce the Dynamic Range of an image taken in sunlight with a digital camera?

3) Why do most cameras have IQ reducing AA filters when the few cameras that don't have them jump in IQ and moire is nowhere to be seen in 99.99% of the images?

4) What is the optimum resolution for small camera sensors? High resolution sensors seem to add significant file size for little discernible improvement in resolution, so what is the cut off for a functional and well rounded small sensor?

Doctors are bad for your lifestyle.

A square sensor would be the most versatile format and more expensive than the rectangular.  The reason that the rectangular format rules is its clientale, amateur photographers. High end pros had been using a square format for the last 70 years (at least).

Not that many, lol. Most of the ones we've used have used 4x5 view cameras.

Oh, and the use of plentiful text formatting does not help make a dubious position any more solid.
