Circular Polarizer

[iND]

I need to update my circular polarizer, any comments on the the choices.
Price is not the main factor, image quality is.

(what is Kaesemann)

Tiffen Circular Polarizer

I bought my last circular in Times Square after I lost the original.
Needless to say I paid way too much for a poor quality piece of glass.




Thanks
