I was really amazed at how well this lens worked. In spite of the fact that it is extremely wide angle, there is no noticeable barrel distortion. Of course there is perspective exaggeration, but that is a mathematical fact of wide angle photography. The image is very sharp throughout the entire frame. It is not often that a lens this wide is needed, but when you just can't get back far enough, this lens solves the problem for you.

Extremely pleased with all results to date. Size is a "little bulky" but weight is fine. Looking forward to more use in the future!!

This is my first wide angle lens and I am having lots of fun from 180 degree landscapes to funky close-ups. For a beginner this is great and not too expensive for my Sony Alpha 200.

I bought this lens for a recent trip to Utah and Arizona for landscape shots. This is a fun WIDE lens. At 10mm (15mm eq on my Sony A300) the edges of the frame are soft, but not overly so. When using this lens at 10mm with a subject in close range there is some noticeable distortion. At first, I was not pleased, however, shortly realized that this distortion adds a certain fun factor to some of the images. If the distortion is bothersome, simply zoom out to about 14mm (21 mm eq) and the distortion is gone.
This is not a fast lens at f/4, but it is not terrible.
Lens comes with a nice carry pouch/bag and both lens caps. For what this lens does in this price range, this is a fun lens to have!

I am so impressed with what Sigma has managed to do with this lens. For such a wide angle, this has remarkably little distortion. I got this to shoot architectural interiors, and having vertical lines stay straight is important. The lens has to be stopped down for sharpness and DOF, so it's a very slow lens. The damping on the zoom and the solid construction are a real plus.

I'm not impressed with this Lens. It's not too bad, but I'm not satisfied.

Purchased for a trip to south-east Utah. Performed very well (it can't make the guy behind the camera a good photographer--darn the luck). There is some light falloff around the edges and if you use P series filters the polarizer will cause vignetting (not a real big surprise) until you get out to ~12mm. I didn't really have a problem with the lens cap (like some) because I generally put a filter frame or filter ring cap on--but a cap with inner release tabs would be nicer.

This lens came in very handy on a two month excursion to Europe. It is surprisingly versatile for landscape, abstract, and city use. It has no distortion whatsoever if used correctly (kept level mostly), and produces very vibrant colors. As any wide angle lens can be, it is prone to flare, especially when used with a UV or protective filter, so they are not recommended. It can be somewhat soft at times, but it is not a deal breaker. Build quality is excellent, as all Sigma EX lenses possess.
