as you can see its a nice diference. I was only playing with it for a minute or 2

and here is a shot i took today

[ALT1MATE]

Have you used any other brand before the Kaesemann? From my experience I can't tell the difference between a Circuit City Sunpak CPL and a Hoya S-HMC (minus flare). The polarizing film seems to produce the same results.

[DonJuanMair]

I have a hoya it was around 40 dollars and i dont get results like this on it to be honest

[Tsmith]

I indeed noticed the difference when switching from a cheapo Tiffen to a Hoya Digital Pro 1. Color and just seemed to stand out better. As for that I now have the B&W Kaesemann and love the results.

Im a bit confused as I just read from the Hoya website that there is no difference between all CPLs no matter what the make. Here's the quote from this link:

http://www.hoyafilter.com/products/hoya/hoya-02.html

"To insure consistency in glass manufacturing, Hoya uses a furnace called an Automatic V blender to mix the different materials at a highly controlled rate. This process creates glass that is pigmented all the way through. With pigmented glass there is no chance shifting over time. There is also no chance of delamination. Also, the two surfaces of the glass are ground and polished for perfect flatness.

The only exceptions are Polarizer and Circular Polarizer filters. No matter the brand or quality, they all are made of a polarizing film, or a polarizing film and quarter wave plate in the case of the Circular Polarizer, sandwiched between two layers of glass."

[DonJuanMair]

you read from the hoya website that there is no difference between all CPLs no matter what the make.

That sentence sells it for me.......

[TaDa]

I had a good Hoya CPL and bought the B+W. Night and day difference. The Kaesemann is built like a tank and the mounting threads don't budge when you're turning the polarizing element. My hoya would start to unscrew if I turned the CPL couter-clockwise to adjust for the image. The B+W just sits there and lets the polarizing element turn. Also, not all foils are made equal. The shots from the B+W are much richer than the ones that I used to receive from my Hoya.

[lukeap69]

@TaDa

Is your HOYA CPL the PRO 1 version? I was thinking of getting couple but this might change my mind to B+W.

The construction may be the same, a sandwich of glass and polarizing film, but like the glass used in the sandwich, the polarizing film used by different manufacturers may vary in quality. The coating of the glass in any particular filter line will also have an influence on the end result. So, no, you can't expect the same results from a cheap polarizer as from a top-of-the-line one.

Yes, it was a Pro1. I'm not saying that it's a bad CPL at all. It was great. In my opinion, the B+W is just better

[Wilt]

A highly detailed brochure from Schneider about polarizing filters and Kaesemann filters...it makes it obvious that there are different grades of polarizers made for various purposes (non photographic), with the different wavelengths of light that are affected, and information about the construction of the partial wave element that modifies the polarized light to make it a circular polarizer...

www.schneiderkreuznach.com/pdf/filter/kaesemann_katalog_e.pdf

Unfortunately, it is not a marketing piece which helps a layperson understand (or to confuse them about...) "How much better optically is a Kaesemann than an 'ordinary' photographic polarizing filter?" apart from mentioning sealed edges.

[4x4rock]

Can you post a shot taking with both CPL for comparison?

Thanks

[DonJuanMair]

i can yeah, but one will be on my kit lens and tje other will be on the 17-40L so there may be a difference there

[Wilt]

i can yeah, but one will be on my kit lens and tje other will be on the 17-40L so there may be a difference there

You could just try and hold the larger filter in front of the smaller diameter lens, for comparison purposes.

[lukeap69]

Yes, it was a Pro1. I'm not saying that it's a bad CPL at all. It was great. In my opinion, the B+W is just better

Thanks TaDa. I will get the B+W instead. It's not an everyday purchase so I think I can spare few bucks more.

Kaesemann is a particular type of Polarizing element which is incorporated into some polarizing filters -- but not all -- built by Schneider (the lens maker), who is the corporate parent of B+W. (Heliopan filters have Rodenstock as their corporate parent, and Schneider vs. Rodenstock is a very long established competitive rivalry in lenses, particularly for large format and enlargers

As I also included in message 13 of this thread, more about Kaesemann can be found here http://www.schneiderkreuznach.com/pd..._katalog_e.pdf

[ben_r_]

Yep! They are awesome!

[jsinon]

I should be receiving my Kaesemann any day now, can't wait to give it a try. Ordered it from hvstar, best price I could find with a lot of people here buying their filters from them. The wait is killing me. Hong Kong is just too far away:(

[Tareq]

I have a B+W CPL that i don't need it, i ordered it with a friend [for himself as well] before i travel but i found that i don't need it as i have another B+W CPL that doing better, just i thought that new one [F-Pro] will be thin and slim enough but it wasn't, so i want to sell it now but not sure where and how.

[DonJuanMair]

Tareq what's the size, I'm after a 58mm one

No.

[CameraBuff]

Good example - Took your advise argyle, My B+W Kaesemann CPL is on the way from HvStar - next, a filter system and some GND's.

[DonJuanMair]

once i receive my 58mm one i will do a test whether the b&w is much netter than the hoya

[DonJuanMair]

thought id show this one too

I have the B+W KSM SLIM CPOL as well, it's quite awesome. Nice pictures. The main thing about these filters is the price. Nearly $200 for a 77mm, but the color saturation is worth it.

[mdr]

Will an 82mm (non-slim) B+W Kaeseman CPL vignette on the 16-35mm f2.8 II on the 5D?

[Morlow]

Still learning here; in a nutshell what does a CPL do? I just bought a couple GND filters for landscape shots. Is CPL basically the same thing just for the whole picture or is there more to the story?

I suggest you read "The Camera" by Ansel Adams.

I'll skip the technical explanations and give you the results. 99% of the time a CPL is used to remove reflections (from glass, water, etc.) and/or darken skies and increase saturation. The other 1% of the time people are probably using one to decrease shutter speed. For example, I'll often use one to cut an extra stop or two of light when shooting running water, to help get the silky smooth look that goes with a slower shutter speed.

A quality CPL is indispensable; I personally carry one with me at all times. The only "differences" you'll see between the various filter brands will be a result of build quality. More expensive filters usually have coatings that increase light transmission and help reduce flare.

[Wilt]

Nice! So I guess vignetting isn't much of an issue using a CPL with the Canon 10-22? Did you get the slim or normal version?

The greater issue with UWA and CPL is that the lens sees such a wide arc of the sky, that the CPL is less effective at some angles to the sun vs. other angles and this is readily seen in shots with wide expanses of sky. Note in the example that only a narrow section of sky was visible, but trees filled in the rest.

[Sauchterlonie]

Are you guys using the 77mm or the 105mm? Just asking as I'm thinking about getting a 105mm to work with my Lee filter holder system.

Cheers

[Tareq]

Because of CPL confusion i don't use CPL at all long time ago since 2007 or 2008, not sure if i should use a slim version or KM version or Pro or HD or 105mm? I have B+W 2 filters but both are the same, just one is for UWA but i can't use any other filter and the other is normal thickness [F-Pro] and has vignetting.

[argyle]

Here's an example of what Wilt was mentioning above with regard to UWA's and CPL's. This was a test shot taken quite some time ago with a 30D/10-22 @ 20mm, with a B+W Kaesemann CPL (non-slim) mounted on the lens. Because of the lens' very large field of view, you will get areas of dark and light across the sky. Sometimes this works with the composition, other times it doesn't.

[s2kdriver80]

Right that is true, thanks for the illustration. But I was wondering about vignetting. If I want to shoot at 10mm with the 10-22 lens, would I have to go with the slim version or can I get away with using the normal version?

[argyle]

Where'd you get yours (if I may ask...)

The Kaesemann is a specific model of CPL. The term 'Kaesemann' just means that the filter edges are sealed to prevent the ingress of moisture between the glass plates. I believe that Heliopan also makes a Kaesemann model. My wild ass guess is that Kaesemann is derived from 'encase'...

So the Kaesemann model has absolutely no bearing on the optical/image quality properties and only has to do with just the build quality/durability of the CP filter?

[Jdmhood]

Yep, the B+W Kaesemann seems to be one of the best CPL you can buy. A review by lenstip.com rated it #1 against 24 other CPL by major companies.

Another CPL worth looking at is Marumi Super DHG. I got one after Andrea @ 2filters.com recommended them to me. The Marumi Super DHG tied the Kaesemann for #1 in the same review linked here. (http://www.lenstip.com/115.24-article-Polarizing_filters_test_Marumi_DHG_Super_Circular_ P.L.D_72_mm.html) They're quite abit cheaper then the B+W unit which kind of surprised me. But hey.. it's that good ;)

I put them to the test yesterday after receiving them Thursday. I hiked up Stone Mountain in Georgia (boy was it a mistake hiking up with 30lb of photography equipment).

Here is one photo i took with the Marumi filter on my 11-16 tokina f/2.8. Straight from camera. No editing done except changing camera profile to Canon Landscape.

That depends on the filter. If you stick with B+W, the standard F-Pro MRC polarizer will not vignette (I don't recall any vignetting when I had my 10-22). There are threads on this peppered throughout the forum...do a search and they'll come up. I also use the same F-Pro Kaesemann filter on my 17-40L/5D2 without any vignetting.

[argyle]

Not necessarily. According to B+W, the K version incorporates higher grade polarizing foils. There may be a slight increase in optical quality, but whether you'll see an appreciable difference with the naked eye I couldn't say.

That's good news since I'd like to avoid the slim version if possible, since you can't use the stock lens cap and is more difficult to turn the filter. So I guess if I were to pick up the B+W MRC 77mm Kaesemann CP filter (non slim), I could use it on the Canon 10-22 with no vignetting issues?

to be safe, i bought the B+W slim version and have not seen any vignetting at all with my Canon 10-22.

i remember reading somewhere that a slim CPL is better for UWA lenses to prevent vignetting?

Extract from Schneider-Kreuznach (who owns B+W) technical information:

"The process used for the manufacture of Kaesemann polarisers was first introduced by Erwin Kaesemann in 1955, since then it has been continually improved.
Compared with conventional polarisers Kaesemann film polarisers are distinguished by their consistant neutrality of colour and excellent polarisation properties. They can be produced in practically any size required while retaining a high degree of mechanical strength. The polarisers are produced from high polymer, light transmitting colloidal film made from polyvinyl alcohol (PVA). The film is subjected to a stretching process which causes the rod shaped molecules in the film to become aligned in parallel so that it behaves like an optically uniaxial crystal. This forms the supporting structure for the polarisation matrix itself which is made from a light absorbing substance. This is deposited on the film by a dyeing process and produces dichroic, i.e. direction dependent, absorption. To protect the polariser it is either covered on both sides with cellulose acetobutyrate (CAB), known as a Type P film polariser, or it is cemented between sheets of glass, designated a Type KS. Retardation films are manufactured in a similar manner, but without the dyeing process.

"KAESEMANN circularly polarising films are Type P plastic films with the addition of Lambda/4 retardation film at an angle of 45°. Kaesemann polarising glass filters are film polarisers which have been cemented directly between pairs of optically flat, low-stressed glass covers. Appropriate edge sealing keeps the filters secure under tropical conditions and free of haze. The average refractive index is 1.52. Our filters are resistant to temperatures of up to + 80° C (+176°F), assuming heat is applied over the whole surface and not at localised areas.

"The optical properties differ according to the application (note: various models of Kaesemann filters are made for a variety of non-photographic applications). This applies equally to the degree of polarisation as well as to the transmittance and the surface quality of the glass covers. This results in a variety of different filter types, of which only the standard series are described here. The optical properties differ according to the application. This applies equally to the degree of polarisation as well as to the transmittance and the surface quality of the glass covers. This results in a variety of different filter types, of which only the standard series are described here.

"The polarisation filters are glued into the mountings so that they are not under stress. The diameter and height of the matt black, anodised aluminium mountings are manufactured to DIN 19030."

Yes. I took this test shot in my yard a few years back when I had a 30D/10-22 in order to check for vignetting. Shot was taken with the B+W F-Pro Kaesemann MRC polarizer, lens set at 10mm. Other than a bit of light fall-off in the upper left corner (mainly due to the position of the sun), there's no vignetting.

I only use B+W F-Pro Kaesemann polarizers, and an assortment of Singh-Ray polarizers. As far as non-K goes, can't help you there. However, I would venture to think that the F-Pro filter ring dimensions are 'standard' for both K and non-K versions...but if you're really worried about it, you'll have to contact B+W for confirmation.

Thanks - yea I wasn't worried about the thickness as the 70mm focal length is narrow and long enough to avoid vignetting on my 70-200 f/4 lens. Was just wondering if I could expect the same optical/image qualities from the 67mm thread model as the 77mm thread model from B+W.

Maybe I will keep them after all.

Here are a few images taken with a cheap Hoya CPL. Does anyone think the expensive B&W Kaesemann CPL will make these images better?

I doubt it will make any difference, but the quality build of that B+W is worthy for me, and maybe by pixel peeper they may say that they see a slightly difference, then not sure if that will worth the more bucks over the Hoya one.
Nice shots though!

Yes, the quality of the hoya rings is not very good. That would be the main criteria to look at b&w. I think most people would be hard presssed ( ie: not possible ) to tell the difference between images made from either brand.

That shouldn't be the deciding criteria...there's more to a filter than just the 'look' of an image. The Hoyas have certain characteristics, and build quality, to make some people hesitant with buying that brand. The Hoyas are known to be difficult to clean, certain Hoya polarizers come apart unexpectedly, they're not available with brass rings, nor does Hoya manufacture a Kaesemann version, etc.

What happens when you're out in the field and accidentally get body oil on the filter and any cleaning attempt just makes it worse? Or you reach in your bag for the filter, and it comes apart in your hands? You can rationalize any situation to make it suit your needs, even if that situation is buying a 'cheap' CPL. The bottom line is, over the long haul, the higher-quality filter (as with most other high-quality items) will generally perform better and last longer. You may pay more up front initially, but over time that cost will average out much less than the cost of having to replace a broken filter once or twice (or, for that matter, losing precious time trying to get the filter clean, while missing an important shot).

Just recieved my B+W KSM CPL today! Too bad I don't have my camera for a bout a week so I can't use it. Anyway, I've noticed I can move the front of the filter up (kind of like a gap) from the treaded part of the filter. Its doesnt feel like its going to come apart, but I didn't think it could move up and down like that.

Does anyone else's do this? This is my first CPL!

Not sure you mean, but on a polarizer the front section can be rotated while the rear section stays attached to the lens. is this what you are seeing?

[ninhja]

No, I mean that, the front section that rotates can be seperated fom the section that stays on the lens ever so slightly. Its not going to pop off, but it does seperate a little when you hold it like a slinky and pull lightly in opposite directions

sorry if i'm not being too clear

[krb]

Never noticed that on mine, but then I've never pulled on any of them like that.

[V-Wiz]

There was a very small amount of play on mine too. Dont worry about it. If it was that tight it woudnt rotate easily.

[ninhja]

thanks V-Wiz. Just wanted to make sure that was pretty normal.

Interesting thread and interesting to note they are still sandwiched, I was shooting with a motion camera up on the north slope in Alaska and if I remember right it was 60 degrees F below zero. My assistant put a 6.6" x 6.6" Harrison and Harrison 85 filter in the matte box and within 5 minutes it crystalized. so we rehearsed the shot and put the 85ND 3 in the box, got several takes in the can before that one crystalized and we were done for the day and headed back to Anchorage. We were at that time told it was because of the laminating process that the different materials contracted differently. Anyway, production had to buy the rental house some new filters.

I just wanted to verify. The 77mm KSM CPL non slim does NOT vignette at all at 10mm with the 10-22? I just bought the slim version, and it's a pain in ass trying to work with it and the lens cap it comes with. I might just pick up the regular one if it doesn't vignette. Thanks for the help.
Sorry for bringing up an old thread.

Yep. It def does not! When I had the 5D and 16-35 II I bought both the slim and standard F-Pro 82mm B+W KSM CPLs and noticed no difference between the two. I then learned that NO B+W F-Pro filter will vignette on ANY Canon Lens on ANY Canon body.

[scubasteve03]

Thanks for the reply. I am going to try to exchange it for the non slim version. I can't believe how slim this guy is. Plus the whole lens cap that it comes with won't stay on even when pointing the lens slightly down. Can you think of any reason to keep the slim version? They were both the same price at maxsaver .net.

Has anyone had any experience using the 77mm KSM CPL on a UWA lens with Lee grad filters? I wonder if there is any vignetting issues there

I dont, but would love to hear if it does or not because I have been thinking about that very combo.

[Tareq]

It vignettes from about 20mm and wider, so that i am thinking about another option i hope.
