The Sigma 10-20mm F4-5.6 EX DC HSM lens allows enjoyment of super wide-angle photography and it is a very powerful tool for indoor shooting and landscape photography
Wide angle of view (102.4° at 10mm and 63.8° at 20mm) offers the photographer greater freedom of expression.
These are special DC Series Lenses designed so that the image circle matches the smaller size of the image sensor of most digital SLR cameras. Their specialized design gives these lenses the ideal properties for digital cameras, the compact and lightweight construction is an added bonus!
Three SLD glass elements are employed for effective compensation of color aberration, which is a common problem with super-wide angle lenses. One piece of glass mold and two hybrid aspherical lenses, offer excellent correction for distortion, as well as all types of aberration.
This lens is equipped with an inner focusing system, and the models which are equipped with HSM system provide quiet, high speed autofocus shooting and also offer full time manual focusing. It has a minimum focusing distance of 24cm (9.4") at all focal lengths. The non-rotating lens barrel perfectly suits the petal shaped lens hood. A circular polarizing filter can also be used conveniently.
Vignetting will occur if the lens is used with digital cameras with image sensors larger than APS-C size or 35mm SLR cameras.
landscape shooting, interiors, perspective shots. nice solid quality, no complains
I shoot as a semi-pro with a Canon 7D. The studio I work for does all manner of photography, from weddings/special events to real estate, fashion, school portraits, etc. I bought this lens to use for weddings, real estate, and for my own artistic work, like landscapes and urbex/architecture. I looked at the Canon as well, and for me, this was a better value. It is very sharp, and the auto-focus is quick and quiet. At 10mm, it does produce barrel distortion, but that can be fixed in post, or it can be left alone for that effect, which looks nice for certain things anyway...at 20mm, it has very little noticeable distortion. Two things to be aware of with this one are lens flare, which is easy with such a wide lens ( just compose accordingly!)and the slower f/4-f/5.6...If you need or want better low light ability, you'll have to spend a bunch more. I just did a wedding with this, ( and several other lenses, of course!) and with my external flash it performed beautifully, so for me, that speed isn't worth the extra $$$. I have also done night shoots on my tripod and gotten similarly great shots with it. I could have rated it a four for those reasons, but for WHAT IT IS, it really is an awesome lens. If you need wide and shoot on a cropped sensor, try this one!
The perfect landscape lens and special effects. The weight is well balanced with the Cannon Eos 60D. It feels like the lens and camera body is one really one unit, not top heavy.
As the majority of my shooting occurs either outdoors in full daylight or from a sturdy tripod, this lens represents an outstanding value in the ultra-wide category. Autofocus speed on this revision is far more speedy and accurate than the one I had a few years ago, even in lower-light situations. This newer one does not suffer the annoying back-and-forth seek chatter that plagued the earlier one, and the motor itself is more quiet than the previous. As it is, most of my use of this lens is by manual focusing, which is plenty smooth and easy. The smoother finish is easier to keep clean, and does not seem to hold onto dust and dry skin ruboff like the previous version. As someone who does not use this lens for sports action or wildlife or motorsports shots, and the like, this lens has performed admirably in all situations I've put it to. Coupled to an EOS 50D, I have always had sharp images with good & balanced color rendition. Chromatic aberration has yet to rear its ugly head in any of my shots, while a CPL filter will do wonders for outdoors and reflective subjects. With financial circumstances forcing the sale of my previous copy of this lens some time ago, I am actually glad now to have acquired this newer one. It's simply more refined in tangible ways, and is an even better value now with current prices being what they are. If you simply MUST HAVE the "near-L" reputation of Canon's 10-22, then buy that. It's unquestionably an excellent lens. However, if you're like me and desire a great 'bang-for-buck' alternative, this one will not disappoint. Consider also that this lens is overall smaller and weighs noticeably less than Canon's 10-22, which can be considered as a feature.
I bought this to work with my 60D and I could not be happier. When I am on vacation, this allows me to take nice photo's of the large Cathedrals in Europe.
I got this lens mainly to take pictures of landscapes and skys full of clouds, I got exactly what I was looking for: distortion (without very much if any loss of focus at the sides) around the edges for a more dramatic appearance and an extremely wide angle. I can capture nearly half the sky in one image!
This lens was exactly what I was expecting. It takes GREAT pictures. Very tight and well contrsucted. This is my first Sigma Lens, but I am ready to send all my Canon Kit lens and Canon Telephoto to the lens boneyard. I will definitely be replacing them with Sigma Lens.
I thought about this lens for a long time. Really wanted to get in to wider angle. Thought about the usual things, 3rd party lens, focus issues, yada yada. Well, I decided to go for it. The lens is impressive. The dynamic range of this glass is not to be taken lightly. I think these 2 images will explain.
Purchased for wide angle astrophotos. Very sharp, with good color correction. Just a little vignetting when wide open.
great for Christmas photos. very handy wide angle lens. At times the shade gets in the way of the flash on the camera on very close up picture. Very useful for documenting and architectural pictures of houses and rooms.
