I am thinking of buying the Sigma 10-20mm f4-5.6 EX DC HSM Nikon fit lens for my D40.

Question is should I get a circular polariser for it, I've heard that these filters can produce odd results at a wide angle?

I had one of those lens and tried to use a cheap polarizer on it. The field of view is so wide that the darkening of the sky by the polarizer was not consistent through the frame. I later borrowed a 200 buck polarizer to try out. It was better but still wasn't up to the task. The cheap one would actually block the corners! The expensive thin one only did that a little. :)

I occasionally use a Kenko Pro1 Digital circular polarizer on my canon 10-22mm and it seems to do the trick pretty well.

That was my experience as well.
I have the sigma 10-20 and can post some pics later tonite when i get home from work which were taken with the Hoya Pro Circ Polariser (same as dave's Kenko just a different label).
Yes, there is odd "banding" when going extreme on the dial but depending on the subject and composition can be good or bad.
You can also dial the effect down a tad and the banding is lessened.
You can't beat a supa-wide dusk sky with it.

here is one shot i forgot was already in my portfolio.

This is the filter and from the same place I got mine from eBay.
About half price retail.

Thanks Ryan, was that with an ND Grad as well or was the sky dark enough?

the polariser darkens it for you.
I dodged the foreground a bit i believe.

OK, bought one, my first shot with this lens and a circ pol'.

Even though this doesn't show the lens off to it's best ability (i.e. tall buildings etc.) I am very pleased with it!

Thanks for the advice everyone.

The "banding" has nothing to do with the quality of the polariser btw. The banding is the effect based on the angle the part of the sky is in relation to the sun - those parts at 90 and 270 degrees if the sun is at 0 degrees darken the most... It is just that with a field of view being so large at the 10mm end, the banding is visible in a single photo.

It is eerie how similar these locations are :-)

I use this lens about 35% of the time...and with a circ pol a lot. This shot was used with both. You do get intesting effects super wide occasionally, but all can be corrected in post. Don't let the "occasional" stop you. I have a very nice B+W Circ Pol. and would recommend the nicer route....
