Circular Polarizing Filters, the good, bad and ugly??

Hi All,

I am about to splash out and buy a cirpolarizer after my other one busted the glass and i was in the shop looking at options and there are too many.

So i am asking you guys, what do you use and why ?

Do u notice the different in quality or not.?

Best Brand?

How much ?

Examples ?

Cheers Neil

Many people, many answers.
General consesus though is:
buy multicoated filters (no matter if polarising or other). It reduces flare and keeps contrast.
good brands are generaly recommended. f.e. : B&W, Hoya (Pro line, but apparently the HMC line is good too) but have a look at Kenko and Marumi too.
anothe thing is, it all depends on the lens(es) you have. Saying goes the lens is only as good as the filter you put on it. So if you have DA18-55 the filter won't degrade the IQ as much as if you would have say FA31ltd.

PS: my own opinion, it's worth to spend money if you are buying whatever! I've learnt that on lenses. The cheap ones are hard to live with and even harder to get rid off! The expensive ones deliver the results and keep their resell value.

The B+W Kaesemann line are very good. If you have an older film camera you may be able to use a Linear (Top) Polarizer instead. They sell for about a third of the cost, compared to a CPL.

+1. There isn't any pressing reason to use a circular polarizer on a Pentax DSLR.

You need a circular polarizer for digital. Get a good one....especially since you live in Oz. Hoya HD or Kenko Zeta..they are the same but the Kenko is cheaper. These are better than the B + W's. They are coated like a Pentax lens and easy to clean. Not so for B + W.

From Hoya:

"Light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camara lens. They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also saturate colors and increase contrast. Polarizers come in two variations but have the same effect. Linear polarizers work with older camera meters; Circurlar polarizers are designed for today's newer split-beam metering systems used in auto focus cameras. Check your camera's manual. Hardened Glass: Hardened optical glass that has 4 times the breaking strength in ANSI standardized testing (ANSI Z80.3 : 2001) where a steel balls of varying size and weight were dropped from a height of 50 inches onto the glass. High Transparency Polarizing Film; The polarizing film is the same as that used in the latest high definition LCD TV screens. It has 25% higher light transmission than standard polarizing film used in current photographic filters. Hardened 8 Layer Waterproof Multi-Coating That is Scratch & Stain Resistant: Newly developed industry leading 8-layer multi-coating yields an average light transmission rate of 99.35% between 400 and 700nm (visible spectrum). These coatings greatly reduce reflections off the surface of the glass allowing you to capture more light in your photos. "

Great info guys.
I need a 77 and 82 and collectively it is over $400USD ! GULP

Now, the whole reason i wrote this is that i had the cheap 77 (which broke )but i used it for waterfalls and loved it.
Especially because it cut out some light which made for longer exposures and better softer water effect.

Soooo. I am wondering why i want to pay the extra when i was happy previously but maybe i will be happier too ??

This link was posted in another thread discussing filters:
Polarizing filters test - Introduction - Lenstip.com
Probably more info than needed, at least for me. Page 4 has the results and summary.
I have B&W and Hoya coated CPLs. IQ is still under investigation, B&W products have meticulous quality, newer Hoya filters seem to have increased, oily residue around the edges (is it just me ??) which makes them difficult to clean.

The HD is different than the regular coated Hoya. Kenko Zeta is the name they sell them under in Japan. http://www.kenko-tokina.co.jp/e/pie2008/zeta_filter_english.pdf

I am with ya on the residue in the corners I use Kenko happy with the overall results (they are Hoya's ) but a #&#$( to clean especially the edges. I might spring for a B+W or Singh Ray but man oh man the price difference

Buy yourself a 82mm polarizer plus a 82mm/77mm Step down Filter Ring, one size fits both.

Pentax DSLR cameras do not use split beam metering systems. The AF is the only thing using a beam splitter (the mirror).
Metering is done off the focusing screen, just like they've done it with every SLR camera, film or digital, except for the LX.

Whoa !!
Is there such a thing ?
Maybe a great idea if the filter does not interfere with the hood.
I'll look in to that.

If you buy a Cokin holder you can use their or Lee's hood system.





If you are buying for a Pentax digital, and the 82mm lens in question is a 135 format lens, I would go the other way on the rings, 82 to 77mm step down and a 77mm CPL. You then wouldn't have any issues with the lens hoods.

I'm using a 86 to 77mm step down ring on the Sigma 170-500mm on the K20D so that I can use my 77mm accessories.

Thank you
Russell
