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

 Yes virginia there is a focusing issue w/ this lens December 31, 2008
Capt Jimmy
When I bought this lens for my Canon 450D, I did not do enough research about the poor quality of Sigma lenses. My suggestion is to take a look at Canon's 28mm EF and 35mm lens as possible alternatives to this lens. Like other reviewers my instance of this lens tends to focus in front of the subject I want and not on the subject. Thus, resulting in an out of focus/fuzzy picture. I've been forced to manually focus this lens if I desire my subject to be in focus. This really reduces the number of photos I can take per given amount of time and the situations where I can use this lens.
An ideal lens for everyday use December 29, 2008
Hussain Alhelli
It's small and light. 30mm/1.4 on a 1.6x crop factor is ideal for indoor photography when you lack space and light.
Image quality is not the sharpest (especially wide open) but good enough for non professional photography.
I find that I have to correct and increase color saturation almost all the time when post processing photos taken with this lens.
I could only compare it to Canon's 50mm/1.4 (I know it's a different length and use) but that's the closest I was able to try (at this price range). The canon is sharper and the colors are much more vibrant. The bokeh produced by the canon lens looks better to me. Again, since it's a different length it can't be used in the same places as the sigma.
Overall it's a nice and humble lens that helps you make the shot instead of missing it.
 A wonderful lens for background blur December 8, 2008
G. Morgan
I've been using this lens with my 20D for the past couple of weeks, and it's so much fun that I've hardly used any other lens. I really enjoy the beautiful, smooth background blur that it gives me at f/1.4. And the sharp areas of the photo are very sharp, even wide open at f/1.4. The build quality is solid and the focusing ring is smooth, which is important for those who sometimes wish to manually focus or to use the lens' full-time manual feature to manually adjust focus even when in autofocus mode. I also find the lens to be very resistant to flare, which is great because I enjoy using it to shoot into the light and get a backlit effect on my out-of-focus background.
This lens is intended for use only on cameras with APS-C sensors such as the 10D, 20D, 30D, 40D, 50D and digital Rebels, and it gives you a "normal" field of view (similar to the classic 50mm focal length on film cameras).
As has been reported here and elsewhere on the web, some copies of this lens have poor autofocus with Canon cameras. The first copy Amazon sent me had erratic autofocus and I returned it. But the replacement copy is superb. And Amazon's returns process is so painless that I felt quite comfortable buying this lens here even though I knew before I bought it that I might not get a perfect one first time.
If you are looking for a general purpose, "normal" lens (the equivalent of a 50mm lens on a film camera) and you are not seeking background blurs, you might also want to consider the Canon 28mm f/2.8, which costs about half as much as this lens. But if you want to shoot at a wide aperture with subjects that are relatively close in order to get a beautiful, smooth and out of focus background, look no further -- this is the lens for you, and the quality of the blur is terrific.
Love this Lens! December 6, 2008

This is my first Sigma lens and I was a bit nervous when ordered it. But I was pleasantly surprised with the build quality and sharpness of this lens. I experienced no AF problems. This lens AF as good as any of my Canon lens. It is very usable at f1.4 and becomes extremely sharp if you step it down a couple of steps. The 30mm works extremely well on a crop frame body especially indoors where there is simply not enough room to step back to fit everything in. Oh yeah, I love the fact that it comes with a matching finish hood!
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.
