| Is it worth the money buying an expensive name brand polarized filter? Or are those cheaper ones you see on Amazon or eBay just as good. I need one for my Sigma 10-20mm I just bought. |

You've spent a lot of money on glass, don't go denaturing your investment with cheap filters. Polarizing filters are laminated from two pieces of glass with a film between them, and the cheap ones are often inferior. Anyway, you need a "low profile" or "thin" polarizer or it will vignette at 10mm, and none of those are especially cheap glass, as far as I know. So shop for a good price on a thin one and you should be OK. Plan on spending at least 75 bucks, I'd guess, though I haven't priced them lately.

| I've got one of the Hoya models and use it with my Sigma 10-20. Works great, no vignette. Couldn't be happier with it. |

| What Bear says. Best to go with a good brand low profile CP. Can't go wrong with a Canon or Nikon CP and B&W makes a good one as well. Spirit likes the Sigma so maybe that would be the one to get. Shop around though and you may find a good deal somewhere. |

| Hoya makes good CP as well. They have different grades of filters so look for multi-coated and slim in the description. The lower grade ones don't cancel out reflections very well and may not produce the best results in other situations where you want more saturated colours. |

Sorry, I would have been more specific with which model I got had I had the information available.
I got this one.
The only time I saw any vignette was when I tested it out, purposefully putting it on top of the clear filter I use to protect my lens from all the crap when I'm in the wilderness, cause wiping a lens on a windy cliff isn't so good on surfaces. Even then, with a clear filter below it, I got very slight vignette at 10mm which resolved completely by about 12mm-13ish. Not an issue at all. |
