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).

Photographers that worked with square format, appreciate its advantages and the level of creativity and versatility it offers.

Nah! Use of square format on 120 film was more a matter of graphic designers not being able to make up their (damned) minds about how they were going to use the shots at the shooting stage...

.... they always demanding loads of crop-ability so they could try out different layouts....

... before EVENTUALLY settling on something they could change their minds about !!

Seriously, it wasn't anything to do with photographers. And wasn't anything to do with producing SQUARE pictures either. Square pictures look horrible, and photographers know that better than anybody!

In real life Hasselblad and Rollie shots were invariably cropped to vertical or horizontal rectangles before use. Hardly any pictures were actually printed square...

... except in articles endeavouring, with limited success, to show images where the square format was LESS than disastrous!
