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.

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 ...
Using a Nikon Mount Sigma 10-20mm f4-5.6 on Sony a7R?
Hi guys! First post here, but I've been looking around the forums for a while. Just wondering, would a crop frame lens such as the Sigma 10-20mm on a Sony a7R with adaptor, perform just as well as it would on a Nikon D7000 with a crop frame sensor? Thanks!
From D5000 to D610 or D810, what will fit me better?
I have been shooting with my first DSLR (D5000) since 2009. I am not a pro, just use the camera on my business travels and with my Family (mostly my kid nowadays). My lenses are 35mm 1.8G, Sigma 10-20 and Tamron 90mm f2.8. I believe only the Tamron supports full frame. I believe going to D7100 will not add much since D5000 is already a great camera and the next step would be going to full frame. My budget is around 3.5k (after selling a CAM recorder from Canon) for the body and 1 or 2 lenses. If I go to D810 I will probably get the 50mm f1.8G. If I go with D610 I would probably get either the 28-70mm f2.8 or the 50mm f1.8G + Nikkor 18-35mm. Thanks!
Thank you all! I decided to buy the D810. Since both will require some learning, I decided to go to the pro camera. I like the crop room from d810 and also the bracketing limits, ISO 64 and the 1/8000 SS may be useful in the future. I am sure IQ will be probably the same. Hope d810 does not come with any surprises (I hope Nikon learned with D600).. Also I hold both in my hands and since I have big hands the d810 felt better for me. thanks again!!! Continue Reading
Based on your lens choices and what you shoot I will go for D610. D610 files will be a lot easier to manage than D810. Continue Reading
My requirement specs seem similar to yours: Mostly kids (4 and 1.5 years old), some nature and landscapes. I do own and use by now: D5000 and D600. Lenses: 18-105(dx), Sigma 35Art and Tamron 70-200/2.8 There's what i think: Update to an D7100. The sensor is a huge step forwards plus: You dont have to touch your lenses. If you do a mayor upgrade now, you will miss too many shots, *because you are fiddling with your gear*. Believe me, i know exactly what i'm talking about. Changing lenses and esp. zoom ranges takes a learning curve. You probably don't have that time. D7100 is a plug and play update. It will enhance everything while the impact to you and your gear is not that big. If you want to sink more money, in addition take your family to paris and see how well it works. -Armin PS: http://www.dpreview.com/forums/post/54067239 Continue Reading
Lens for real estate photography
I am in need of a lens for my Canon 70D. Ultimately I would like a Sigma 10-20mm, but also in need of a general all purpose lens. I've also considered something like the Sigma 17-70mm so I can get F4 across that focal range. The only lens I have now is the Canon 50mm 1.8. Would the 17mm be adequate to at least get started? I don't have the money for both.
17mm will generally be enough for most rooms apart from very small bathrooms, etc where you can't "back up' enough, but it is dependant on the client. Generally there's two schools of thought the clients falls in to: a) The photos should be as good as they possibly can be to wow the client and get them to view the property. This is generally for upper-end properties that have a good level of fit and finish, are nicely decorated/furnished, etc... These are the clients where your 17mm might not be acceptable as they want the super wide wow-factor to feel like the person viewing the photo is immersed in the room. The client being wowed by how nice the house looks books an appointment to view. or b) The photos are there just to give enough of an indication as to the general space and layout of the house to get the customer interested in viewing it in person, they don't want to give too much away, they'd rather the bad points be addressed in person by the agent who can steer the ...
