what brand of CPL filter is recommanded?

[kons]

I've got a canon 10-22 wide angle lens recently and I put a hoya 77mm cpl filter on it(the cheapest green brand) but then I found 2 dark corners appeared in the pic.
After doing some research I found out the dark corners are caused by the filter. In order to avoid this problem someone recommands me to get a thick one but I don't really wanna spend $100 dollars on a filter...
If you guys know which brand of CPL is cheap and good (at least not very bad..) Please let me know. Thanks!

Hi Sid, I know how it feels to get a great UWA shot damaged by silly cheap CPLs around.

I currently own a Sigma 10-20mm and I've recent got myself a Hoya Pro-1 CPL Filter. Works like a charm, no flaws that my eye can see during post processing, so I'd highly recommend this filter to you. This should cost you around $50CAN, but if you find that its too expensive to you, you can go one down to the Hoya 77mm traditional CPL filter and that should do you good too.

The difference between the Pro-1 and the normal lies in the multi-layer coating that's present on the Pro-1. Better coat, better coverage and better quality. Just that you pay a bit more.

Hope that helps ya.

Thanks very much Keegsmeister for your advice! I searched the filter right away on ebay after reading your reply but the cheapest one I found was $119----what a headshot...though it's much cheaper than in Canada ($179+13% tax).. I found some brands named Visico and Sonia which I'd never heard before. They are really cheap but I do doubt about the quality...The max money I will spend on the filter is around $80 with tax... It seems impossible to get a good one with this money...

I thought for ultra wide, you need to get a "thinner" cpl to avoid what you are seeing?

You may want to check out hvstar.net - their prices are very good.

I prefer B&W myself because I've never had problems with them. You will find more savings (compared to US) if you go high end Hoya though. $80 is cutting it close for a high end CPL though ... even from hvstar.

Thank very much for the great website. I found a good deal there!
And thanks Keegsmeister. You are right! What I found in the description was "The Hoya Pro 1 Digital Circular Polarizer takes advantage of Hoya's patented optical glass technology to create a hardened glass that is thinner than the normal optical glass. This allows the overall thickness of the filter to be reduced to avoid vignetting when used with ultra-wide angle lenses."
I paid only 76 bucks including shipment.
Thank you very much and I appreciate your help!

Your problem isn't from a cheap filter in this case; it's from a thick filter. You need one that's labeled "Slim" or "Thin". However cheap filters will cause other problems, like distortion or flare. Good brands are Hoya (S-HMC coated), B+W (MRC), and Heliopan (SH-PMC). B+W's F-Pro line, although not labeled as slim, are thinner than most filters; many users find them to work well on UWA lenses.

Whoops my bad. I meant it THINNER! Haha...

I am not sure how fond are you with eBay, but you should be able to get a very good deal over there. I have been shopping over there for over 2 years now and I get most of my photography needs there. Do check eBay out!

Depending on the brand, a slim filter is not always necessary for the 10-22 lens. I've been using a B+W F-Pro polarizer and have never had any signs of vignetting. There's also a Hoya non-slim that behaves the same way, just not sure which one since I'm not familiar with the Hoya filters. There have been a few threads on here with sample pics regarding this issue...try a search and you'll find them.

I bought a Hoya 67mm CPL for my 17, it should be good on the 10-22.
