Cons: 1.prone to be scratched due to its protruding front elements, 2.hood coating will gradually loose due to the frequent attachment and detachment of filter holder, 3.very ridiculous vignette(like a big black circle) at 15mm on FF when the filter-holder attached. 4.hard zoom ring 5.copy variation(same old story from sigma) and sigma stopped producing this lens :(
Pros: 1.sharp enough all through 15mm to 30mm 2.price tag beats the quality, 3.firmly built, 4.AF is sufficiently fast under low light conditions, 5.manly feeling when grab with a Full Frame Camera
Summary: very good lens indeed for the mad angle photography..

Cons: - Not terribly sharp at reasonable apertures. - Visible distortion at wide end. - Not HSM. - Filter awkward to use and causes vignetting at wide end. It's 82 mm to boot. - Flares a lot. - The SIGMA color may be a turnoff.
Pros: - Pretty decent optics. - Built to last. - Useful range on an 1.5x crop DSLR (but I wish it was a bit longer, as I had to change this for a 28-75 a lot).
Summary: I had this on a Minolta DSLR for awhile, back in '06-'07. It had its quirks but served the role of the WA zoom quite well until I jumped ship for Canon. Not sure how it fares on an FF camera but the 15 mm sounds real wide.

Cons: Flare is the biggest issue with lens. Distortion as is to be expected. Cannot mount a filter.
Pros: Solidly built, very wide full frame at a reasonable price point.
Summary: For the price, unless you are a pixel peeper, this is great value lens for a full frame. No it will not stand up to lenses that cost 5 times as much, but then it does not cost 5 times as much. The major downside is it high propensity for flare and the inability to use filters.
