Sigma 12-24 users

I've been meaning to pull my thumb out and update my site, and then add more photos. The one thing that's stopping me taking a certain type of photos is that I want to get some filters of various types. So my question is this: What brand of polariser do you use, and where did you get it from?

I've been googling for the last few days in my lunch hour at work, but I never seem to be able to find any reviews, or even brand names when it comes to items for this lens. I also want to get a poloriser for my 50mm too, so recomendations on this would also be appreciated, but the Sigma is the priority at the moment.

Now you watch, the first person to reply will have found a link on google in seconds to irritate me

Thanks in advance!

Hrrmmm... The 12-24 has a built in petal hood, like my 15-30. Although you can screw in filters to the hood sheath (possibly 82mm? Crazy expensive) they'll cause the edges of the frame to clip totally, severe vignetting. The hood sheath itself will cause vignetting on a full frame body.
That's all assuming that the design of the 12-24 is similar to my 15-30, which I think it is.
Basically, unless I'm wrong, you can't use front screw in filters - which is why there's a wee rear gel holder behind the rear element, and is also one of the reasons Sigma made the 10-20 for crop cameras (which can use front filters).

Yeah you're right. That's why I was asking. The 12-24 has a rear mount for gel filters, which is probably why I'm having trouble finding them. I want to take shots of buildings around my area, and really need a polariser.

Oh, and I've almost finished updating my site tonight, just need to upload photos, and finish altering Coppermines look. www.my-digital-styles.co.uk

I've only added one photo so far, just incase I need to reupload it all after altering the theme to that of my site
