for the "E" : Käsemann filters offer the highest optical quality and are more resistant against extreme klimatologic conditions because the filter is 'sealed' from the inside.

Ok... so E-ones are sealed from inside (and probably also from the outside?) and MRC ones protected from the outsides (and not from the inside?)... so "E" ones are "better"?

I have one of the Käsemann polarizers and before I bought it I found on their website that the glass edge is sealed (not sure the exact process) before the glass is placed in the frame. Which makes sense for a sandwich optic like a polarizer if you expect to use it in extreme conditions.

Meanwhile the MRC coating is on the surface(s) the light passes thru.
