Not cheap, but inexpensive

Unfortunately, polarizing filters with larger diameters do not come cheap. This filter of B + W is meticulously crafted and makes on my EOS 550D exactly what it should: it makes the sky blue, the green green or suppressed at the request very nice reflections, for example on the water or take pictures through glass.

Sure there are NoName polarizing filters at significantly lower rates, they are, in my experience, but usually processed much worse (for example in the thread), visually I can not judge the difference.

But what perhaps speaks for a brand Polarizer: (hopefully) consistent quality in the compensation, after all, sits the polarizing filter at a decisive point visually, right in front of the lens. At least those who should use the polarizing filter more often here but invest a few euros more, casual users are safe well served with a cheaper model.
