Cons: Can't use filters. Careful with that exposed from element!
Pros: Fast f/2.8! Sharp wide open up to f/16, small and lightweight.
Summary: I bought this as a possible replacement for my Sigma 10-20mm. I knew when I purchased it on eBay that it was for FX. On a DX camera it is really just a very wide angle lens with some distortion. I use this on my D90 and correct the distortion in DxO Optics Pro. So far I have been very happy with it. Much sharper then the 10-20mm and fast f/2.8 aperture comes in handy. Though not as wide as my 10-20mm it's wide enough. Here's a set on Picasa I took showing pics with and without DxO distortion correction. https://picasaweb.google.com/WVKayaker729/Sigma15mmTestShotWithDXOCorrectionComparison?feat=directlink

User profile: Semipro
Cons: CA´s quite visible, better for fullformat (APS smaller distortions), AF not the quickest and noisy.
Pros: Very sharp, good corners from f7.1, good buildings, nice colour, best fisheye on Canon 5 D similar to Canon 15, my special price!
Summary: Nice lens! Now the prize fall down, so good value for the money. Woks great on my Canon 5 D, on APS-C smaller distortion and not so wide (like 18-20mm) but as well nice 3-D-effects, very nice colours amd very sharp in the centre. Good prize, buy it!
