This is not a lens I will use everyday but it gives me a great wide option. I have used it for night photography - great.

Used at the moment for landscape with very good results

I've owned this lens since it was first launched as an upgrade to the f/4-5.6 version a few years ago. As I shot a lot of sports and low light at the time I didn't fancy the slower version so waited for this. I've used it for landscapes, architecture, industrial work and even on occasions like weddings for venue shots for shooting large groups in small venues.

The width makes it pretty versatile in a lot of tight spaces and that extra little light gathering afforded by the wider aperture has its uses, although the only time I've found it to be sharp at f/3.5 is when used up very close and you can get a precise focus. Trying to use it at any distance wide open is just a no-go, it gets unusably soft very quickly.

As you stop it down there's some definite improvement, although even at an optimum aperture of f/11 before the diffraction of smaller apertures kicks in, there's still some pretty heavy corner softness... Especially in one corner, which leads me to believe that one of the elements isn't quite correctly aligned. It's been like this since purchase but I've somehow lived with it. It's like this regardless of how good the light is, how sturdy the camera is supported, even using mirror lock up and a remote just to remove any other possible factors relating to softness.

I've used a few other APS-C ultra wide angle zooms such as the Canon 10-22, Tokina 10-24 and the Nikon 10-24 too, all of which outperform this Sigma 10-20mm f/3.5 in terms of overall image quality... And in the case of the Tokina, it beats it on price too. Do yourself a favour, shop around, try different lenses out on your camera and see what works for you. But definitely don't make any snap judgements as far as buying this Sigma goes.

I've used this lens for night photography and it's good and for architecture in general. The lens is excellent for both exterior and interior work. Some find the lens heavy - yes but as a retired professional I'm used to weighty cameras and the lens does reward the user with its quality. For architecture just set the lens to f11 and it gives edge to edge sharpness from the reach of your arm to infinity and no noticeable distortion.
No cons for me.

Excellent build quality, great for landscape and interior architectural photography, significantly cheaper than the Canon equivalent.

Used in conjuction with my Canon 7D this now complements my lens line up.

Having used the standard kit lens a Canon 17-85mm zoon with my Canon 40D I was becoming frustrated with the effective wide angle end of the lens and looked for a wide angle lens to give me foreground impact. I went for this lens with its constant apperture range as opposed to the variable aperture lens from both Sigma & Canon. On first use I was knocked out with the ability to make the foreground objects really dominate the scenes and the fantastic depth of field this lens gives me in landscape work. I also do a lot of theatre photography for an amateur theatre company and this lens enables me to shoot a full record shot of the set without moving from my normal seat in the stalls, previously I had to move further back to obtain this shot. Having shot comparable landscape shots at similar settings with my kit lens and this one I would say that this lens is slightly higher contrast than my Canon Lens.
This lens has given my photographs a shot in the arm and renewed my interest in landscape work and enabled me to choose different viewpoints with much more impact. A product well worth the money.

HSM Focusing is quiet and blistering fast.
Manual focus is easy to use. User can be confident of a sharp image.
Composition and distortion is easily achieved in camera position to subject. Not a difficult feat.
I have 3 other SIGMA lenses and they perform well
would also recommend Warehouseexpress for all your camera needs 10/10

As good as the Canon but a lot cheaper

I like wide lenses so this has become my everyday lens. It works well in combination with my Sigma 30 mm 1.4L. My opinion is that if you can afford L lenses, buy them, but if not go for Sigma. At the time of writing the Canon EF-S 10-20 is 50% more expensive and slower.
