What possible use is a polariser on a lens of this focal length range?
Even at 24mm on APS-C, there are very few shots where a polariser
would give a useful result.

What? Are you serious? What do you think a poloriser does (or does
not do)?



The OP has a point. Even at 24mm on an APS-C sensor, the angle is so wide
that a polarizer is usually useless for darkening the blue sky or distant
haze reduction. At shorter focal lengths it is less than useless for
that purpose if there is lots of sky.

Under certain circumstance it would be useful for reflection reduction.
Outdoors under clouds, standing in front of a lake, yes, it might work
nicely. Indoors looking at a water pool, yes, it would work.

The problem is that at very wide angles the polarizer angle would
need to be set differently for different areas of the scene, in many cases.
