Great Lens...Works on both film and digital bodies!
Very little distortion when used on my D100!

shawn, so heard you can't adapt a uv filter to the front to protect the lens coz of the huge popeye?

Lens come with 82mm filter holder. Attaching a UV filter is possible but vignetting will be inevitable for the first half of the range.
If you are using a 1.5x or 1.6x it is quite ok but you need to get an expensive slim UV filter like the hoya pro 1.
On the performance - it is a very good lens. Provides a very interesting wide perspective, good colours (for such a wide lens) and overall sharpness. But need to be careful on the edges when taking people close as some distortion is noticable.

any wide angle lens will produce distortion when used at close range. even a 35mm lens will distort. for people its best to use a more tele lens.
and some distortion is understatement. lots of distortion sound more like it. thus this is not so much the characteristic of the lens in question but rather wide angle lenses in general...

all lenses will produce distortion, more or less, if the subject is too close to the lens itself. just that it is more noticeable on ultra wides, because the photographer tend to move in closer in order to frame the subject to fill the frame. use the lens on an ultra far subject like a mountain range, and it should look fine. vignette is another thing though...

Heard u need some sort of rear gelatin filter for the lens....wonder how much will that cost, anyway deciding whether to get the 12-24 or wait for the tamron 11-18.....

I think tokina has a 12-24mm also but only 77mm filter so i am hoping to get that....

I am using a Kenko 82mm filter for my 12-24... standard thickness... Personally I find that it is no point to buy a super thin filter cos when the filter adapter is on, the allowable zooming I can get on my D100 w/o vignetting is 15-24mm... If I want to shoot at 12mm, just remove the adapter... which can be removed quite easily...
FYI, a 82mm super thin filter can cost a bomb....and breaks easily!!! My 82mm Kenko filter only cost around $40 (can't remember actual price)
When shooting with super wide angle lens, try to maintain a level between the ground and the lens axis, this will prevent too much distortion.
However, a slight tilt of the axis can result in quite a lot of distortion for a 12mm lens.
I have heard of the new tokina 12-14 wif 77mm filter, if you can wait, why not wait for that to see if it is better than the sigma one...
Oh yes, one more thing....when shooting with the lens w/o the filter, I quite often get some fingerprints on the lens surface as it is rounded and popped out.....
These are just my personal opions about the lens.... hope it can help you with your decision making...
