B+W 77mm MRC CPL vs B+W 77mm KSM MRC CPL

Hey everyone.

Looking at getting a CPL for my new lens and have decided to give B+W MRC a go but there are two versions.

The 77MM MRC CPL and the 77mm KSM MRC CPL.

So whats the difference?

Cheers.


Edit: Apparently the KSM are "encased" for extra protection.

Is there any other differences?

The Kaesemann has sealed edges; useful if you're often in high-humidity conditions as it reduces the likelihood your polarizer will delaminate (polarizers consist of 2 layers of glass sandwiching a sheet of polarizing material). It's your call which to get. I don't get Kaesemann's; I haven't seen even cheap polarizers delaminate on me in many years use, but that's in the conditions I normally work; yours may differ.

Cheers for that jon.

Had to venture outside these forums to find the intial difference.

Only couple of bucks more so might aswell go with the KSM.

Hi,

I bought the B+W 77MM MRC KSM as it was just a couple of bucks more...I really like using to CP with my 10-22MM and my 17-55MM lenses.

I've got a Kaesemann, love it.

I have both KSM and Non-KSM. IQwise no difference. Buildwise excellent. For a few dollars more, I would recommend the KSM version. You never know when you'll need the extra protection.

I have the KSM one. If you get it from hvstar.com the price difference from normal retail is minimal and its worth it for the added protection.
