The 10-20mm F4-5.6 is the cheaper of two Sigma lenses covering the ultra-wide angle range for APS-C SLRs (the other offers an F3.5 constant maximum aperture). It’s a solidly-made lens with fast, silent autofocus, and available in versions to fit every SLR on the market. It’s probably better suited to landscape work than architecture, due to fairly strong barrel distortion at wide angle.

Overall the Sigma 10-20mm F4-5.6 EX DC HSM is a solid, well-built lens with good operational characteristics, which justifies its popularity with generally decent imaging results. While its long-running unique selling point of being the only third-party 10mm zoom has now disappeared, and it faces strong competition from Tamron's 10-24mm, the different characteristics of the two lenses means it's still a good option for APS-C users looking for the widest of ultra-wideangle zooms.

Not So Good For
People who are picky about barrel distortion, or shoot in a lot of low-light environments.
acteally its my amazing lense i found it most great lense than canon its a nice price & perfect lense & beauty color altogh its from big company in lense made the lense is the 2d place after Tokina
My quick review
This lens could be better for the price I paid at the time (€510). I like this lens a lot for the professional feel, colors and of cours the wide angle. Optically my copy has a flaw and unfortunately I noticed it too late. Pros: - Good (not great) sharpness at most of the frame. My copy is decentered and doesn't give justice to it, but the sharpest side of the frame is good at f/5.6. I normally use it at f/8 or f/11 and the sharpness improves significally. - Like my Nikkor 35mm f/1.8, this ...
a great wide angle zoom
After reading plenty of reviews, I bought this lens for HDR landscape photos on my Canon 60D and it indeed is a fine lens. Feels very solid, autofocus is very fast, zoom is smooth, manual focus very smooth too. Have done some great interior shots, minimal distortion and only on the wide end. Great lens for the money too. No regrets. After months of outdoors use, no dust at all internally. Fits the body well too. Problems: none.
A top pick
I carefully researched and read all the reviews of available super-wide zooms before settling on this one. There is a lot of choice now, and each lens seems to have its own strengths and weaknesses. However, in my opinion, this lens is still a standout. The construction quality of this lens is far beyond what one would expect for a lens of this price. It feels incredibly solid, like the high-quality prime lenses of many years ago. Both the zoom and the focusing ring are very ...
Complete upgrade or add to the bag?
Hi, I'm here to get some second opinions on my desire to upgrade or add to my bag. So far I own a Canon Rebel T3i with a Sigma 10-20mm f4-5.6. I have been shooting for long enough and I don't see myself staying within crop sensors any longer. I used to shoot film completely so I need the full frame to fulfill my cravings. However, I also want to have video capability so that I can produce videos as well. Right now, with the T3i and Sigma, I can probably sell the T3i for around $400-500. As for the Sigma, maybe around $300-350. So I can potentially have $700-850 by selling all that I own. I am also a sneakerhead and maybe willing to sell some of shoes for up to $500. So, if I'm willing to sell all of my stuff, I can have up to around $1100-1350. So here's my dilemma. With that potential $1350, I can purchase myself a used Canon 5D Mark II for around $1200 (maybe less if I can haggle). Which means I can potentially have maybe around $200 left. I can then buy a Nifty Fifty or save up a ...
Sell some (useless :-)) sneakers for $550. Spend $450 for a 5DC and another $100 on a 50mm f/1.8 and keep your T3i. Now you have wide angle, portrait, and video capabilities with the T3i, and full frame "normal" with the 5DC. Buy a 6D with kit lens as an upgrade for the 5DC when prices for that camera fall below $1000 (give it a year or two). Continue Reading

I somewhat can't part with this little T3i, it's my first DSLR. Wow, I never thought about the 6D ever. Thanks joejack! Continue Reading
Sell Sigma 10-20mm for used Canon 5D mk1?
Hi, I just need some opinions on what I should do. As of right now in my bag, I carry a Canon Rebel T3i with 40mm f2.8 and Sigma 10-20mm f4-5.6, so I got some coverage in the ultra wide range and the portrait range. However, I'm not quite satisfied in this consumer camera; I have the urge to upgrade to a Prosumer or Professional/FF body. I have a friend who is willing to sell me his used Canon 5D MK1 for $450. I want to know if I should sell my Sigma to own a 5D for portraiture and the T3i as a backup. I've been doing my research on the 5D and it's often quite called a "dust magnet", where you have to clean the sensor yourself. I don't know how to do that yet, hopefully it's something I can do at home without expensive materials or anything, since I don't have money to get it cleaned elsewhere. I used to shoot film so I really like the full frame, but I also want to get into video, hence the T3i. I've considered the 5D mkII but way out of my budget, I'd have to sell everything I own ...
Well, I bought a 5D Mk I a couple months ago, sent it to Canon for the mirror update which included a free cleaning. Since then and multiple lens changes ( I always change with the camera facing down) there is still zero visible dust. I sold my 60D to buy the 5D and absolutely love it. The file quality is fantastic and I can now get back to the FOV I have with my film cameras. I still shoot film and it always annoyed me the my lenses didn't view the same on crop and FF. As for selling you Sigma, only you can answer that. But imho, the 5D Mk I is a fantastic camera. Continue Reading

Especially about how you change lenses facing down (which I will always do when I get one!). I'm still iffy about selling my Sigma though, it's an awesome lens which I got really cheap. It would be really helpful for video and just when I need the wide perspective, perhaps I'll buy a Rokinon 8mm fisheye and see if I can defish the images so it'll still give me ... Continue Reading
Go with a UWA lens or 17-40L?
Hi, so I have some money to blow on some nice new lenses to replace the kits. I find myself doing a lot of landscape pictures, really looking for and want the ultra wide range, to get past that 18mm. But I also want a nice walk around lens. I have $1000 to drop, but would like to keep it around $800 if possible. So my question/predicament is; Should I buy an UWA lens such as the Sigma 10-20 for around $300 and have $600-700 leftover for something else, or Tokina 11-16 and have some $400-500 leftover OR go ahead and invest in the 17-40mm f4L lens and have $400-500 leftover. (which will be great for when I upgrade to FF, which could be next year or 10 years idk). If it helps, I'm very mixed; I like to experiment with different types of photography, but I think landscape/portraits are mainly my thing. Thanks! And I am shooting on a 1.6 crop. Canon T3i.
As for lenses a used Sigma 10-20 and/or Tamron 17-50 f2.8 would strike me as better choices. Unless you have a definite plan for full frame I'd forget that aspect of the choice. I'd not really choose a 17-40 f4 L for landscape on full frame. At the wide end the extreme corner performance is poor and the vignetting heavy. On crop these are not issues, but it's only real advantage on crop is the build - solid as a rock. There are detailed tests of all these lenses on Photozone.de if you want to consider them. As for whether you even need full frame ( few do, IMO ) that's another issue. Continue Reading
If you want wider than your kit lens, I'm not sure why you are even considering the 17-40/4. Buy an APS-C ultrawide and either sell it when you do finally go full frame or keep it as backup along with your crop camera. No use spending a lot of money to get something that doesn't even meet your immediate needs. Continue Reading

No use spending a lot of money to get something that doesn't even meet your immediate needs. I agree with the above and I have also read your other threads. I will add two other comments: (1) If you still have the Canon 75-300mm and you use it, you first priority should be to upgrade to a better quality lens, even the EF-S 55-250mm. If you don't use it, sell it. The 75-300mm is one of the worst lenses that Canon makes. (2) If you are interested in landscapes you should consider getting a good quality tripod and ...
