Just want to know the differences between the two circular polarizers. Are they optically the same?

I beileve that I have read that they are optically the same. The only difference is that the Kaesemann is a sealed CPL. Dust and moisture can't get between the two surfaces.

Opitically yes, but the KSM versions are sealed around the edges of the polarizing film and are therefore built better and to last longer. For the minimal cost difference I went with the KSM version.

The Kaesemann version also uses a higher grade of polarizing foils (according to B+W literature).

This statement is true. I have never seen any tests that demonstrate the value of the higher grade of foil.

Schneider information states, "Compared with conventional polarisers Kaesemann film polarisers are distinguished by their consistant neutrality of colour and excellent polarisation properties."
