Amazon.com Product Description
Designed to match the APS-C size image sensors of Canon digital SLR cameras, the Sigma 30mm f/1.4 lens is an ideal choice for a wide range of applications, including snapshots, portraiture, indoor shooting, and landscape photography. The 30mm lens relies on two special-low-dispersion glass elements and a glass-mold aspherical lens. Combined, the construction details correct for all types of chromatic and color aberrations. The lens is also equipped with a Hyper Sonic Motor (HSM) that supports quiet, high-speed autofocus, but also turns off should you prefer full-time manual focusing. Other features include a maximum aperture of f/1.4, a 62mm filter mount, and a one-year warranty. Specifications

 Great Value, Fantastic Results November 2, 2008

i bought this lens last year before going to England. I kept it on my xti practically the entire time I was there, except for the architectural shots I took with my 10-22 wide canon lens. This prime lens provided very high quality shots with a beautiful bokeh. For the price, i have no right to give this lens less than a 5 star rating; and for sigma to produce a lens with a nice professional matte feel and size- this one is hard to beat. I'm still startled by the amazing clarity and sharpness in my images- it's better than real life to be honest.
Sharp, but with lots of CA (wide open) October 6, 2008

This lens is extremely sharp at f1.4, which is of course the whole point. The problem I have with this lens is the Chromatic Aberration at f1.4 is very strong. I was not able to remove it using Lightroom 2, by this I mean moving the sliders all the way to either direction. This mostly occurs during strong contrast situation, like for outdoor portraits in harsh sun. I did not want to have to put up with the CA from the lens and the slow focusing despite the HSM, so I sent the lens back.
The build quality was very good though.
Outstanding lens - if you get a good copy September 20, 2008

I've read a lot of good things and seen a lot of images taken by the Sigma 30mm f/1.4 lens, so I decided to get one from Amazon. First copy I got was no good. It was out of focus on both my Canon 20D and 350D. So I returned it immediately, and thanks to the good return policy of Amazon, it was no hassle to do so.
I ordered another one. It was fantastic. All I've read and seen about it was true. Now I could take low light pictures without dreading the noise at high ISO with fantastic bokeh to boot and without paying an arm and a leg for the Canon equivalent.
Nice glass September 18, 2008

Lots of glass, which makes the lens a tad heavy. Depth of field is impressive. I haven't experienced the focusing problems that some other people have described. Overall, this is a great lens for relatively dark and/or indoor lighting. As expected with f/1.4, the bokeh is just gorgeous.
 Mis-focus September 6, 2008

I was 0 for 2 with the Sigma 30mm bought at Amazon. Got the first one, focus was terrible. I mean the only thing I could get in focus on my xti was a shot outside at f/8 and infinity. I tried to focus on my birdfeeder at 30 feet and was really blurry (with plenty of shutter speed). Inside was a little better but completely unacceptable compared to my 50mm f/1.8. Sent it back and got another from Amazon. A little better inside. The focus was not so horrible that I could actually tell that it was front focusing. Things that were in focus were very sharp (only a couple of shots of things I wasn't focusing on). Outside I still couldn't get a clear focus on the bird feeder. Oh well, Amazon was great though. No problems with the refund.
Got my Canon 28mm f/1.8 (at B&H) and all of the tests that I did with the Sigma showed that the focus was right on. Taking pictures of my baby girl was hit or miss just like my nifty fifty, but at least I can take sharp pictures of inanimate objects at close and far ranges. Unfortunately, that was not possible with the Sigma 30s that I had tried (on my Xti).
