Re: I'm not sure a polariser will even work as usual

Is this true? or is it maybe the reflectivity of the material. like a chrome bumper being 100% reflective vs a windsheild being only about 3% reflective?

Magnus can probably tell, but since polarisers have no (polarising) effect on metals, and the mirrors in the 500 mm are metallic, will it work as anything more than an ND filter?
