Schneider True-Pol
« on: August 25, 2009, 05:24:18 pm »

Hi,

I shoot outdoors and the polarizer is my main filter.  I get the best I can find and previously used B+W.  I saw the Schneiter true-pol advertised as 12 times more effective than other polarizers.  I have seen from film forums that people like them but no real feedback as to whether they are better than other filters.

I don't mind the 4x4 square as my lenses run from 72 to 95mm and I use 4x6 grads all the time. so I have a rotating holder.  If this filter does give me noticeably better polarization in more conditions then I would definitely be interested.

Anyone have experience with this filter and how it compares?

Thanks

Guy

How are they measuring that?

I don't know, but it comes from a "white paper" on their site.  Because it's Schneider I give the benefit of the doubt that maybe they are better that others in some way, but I wanted to get feedback from someone who has actually used it or who knows someone who has.

Hey Guy, I have the True-pol and use it with my Mamiya 28mm and Nikon 14-24. No way it is "12 times more effective" - that is just marketing BS. I have never done a head-to-head comparison but I doubt you would see much difference between it and your B+W (probably are the same glass to begin with). This filter is VERY thick, but then I guess it is actually thinner than the B+W since it is not mounted - just two very thick sheets of glass.

Doesn't Schneider make the B&W Kassemann filters?  I was under the impression that they were similar - except for the ones advertised water white. But I've been wrong before...    Certainly the B&W Kassemann filter I have is the best polarizer I've used so far.  I was using a cross polarizing lighting technique a while back and the B&W was the only one that completely eliminated the reflections from glossy painting surfaces.  But I have not tried the Schneider... to see if its better or not.

Tim, care to share how you are mounting the filter on the 14-24?

Cheers,
Bernard

Bernard:

The filter is taped to the front of a Cokin X-Pro holder and then slipped over the lens until the front of the lens hood touches the filter. On the Mamiya 28mm I made a foam donut that I attached inside the back of the filter holder (instead of using the universal mount), and that fits over the lens hood by friction - then I could rotate it as needed. With the Nikon I just layered some strips of velcro around the back of the lens hood and on the inside of the filter holder. What I found was that no matter what the light direction, the polarizer was most effective when it was straight up and down on the holder - no rotation needed. That is a good thing since you do get dark corners with the filter on a fullframe Nikon when you rotate it - but none when the filter is used straight up an down. It is an expensive, sloppy, and bulky system but does work on a fullframe Nikon or with the Mamiya and a P-45+.

Käsemann Polarizers aren't better in polarizing, they are rather better constructed, so that the single layers wouldn't come apart, especially when used in humid conditions.

Tim,

Thanks for the feedback.  Sounds like I might spring for one because in the end it would be cheaper than several different sized B+W rotating filters.

There's no doubt it is a great polarizer - my only issue is that I have to hold my breath every time I take it out of the box to use it - I've already dropped one and it shattered on the rocks below - a $400 oops! For all of my other lenses in three camera systems I just use step-up rings and so only need a single polarizer that fits them all...
