Comments about Sigma Sigma 10mm - 20mm f/4-5.6 EX DC HSM Autofocus Zoom Lens for Canon EOS Digital SLR Cameras.:

I really enjoy using this lens. It is very sharp and easy to use manually. I have found the auto focus to be right on just about every time.

Comments about Sigma Sigma 10mm - 20mm f/4-5.6 EX DC HSM Autofocus Zoom Lens for Canon EOS Digital SLR Cameras.:

This lens is very compact regarding its ultra-wide focal length, and doesn't have protruding front element so filters are usable. While vignetting at wide-open aperture at 10mm is a bit too much, it has very low chromatic aberration and good distortion control, making it excellent for landscape photography.

Outstanding product for the price. Good build quality. Rings are a bit stiff for my taste, but for the price no big deal. I take this lens everywhere and use it a lot more than I thought. It's my first Sigma lens and it will not be my last.

As a hobbyist that primarily shoots landscapes and city environments, this is an excellent lens for the price. It is the one of the only ways to get 17mm on an APS-C sensor (the only other being Canon's expensive 10-22mm lens). My main problem with this lens is that auto focus in low light situations is inaccurate, forcing me to manually focus. Since I mainly shoot landscapes all that it requires me to do is set the focus to infinity for my picture to be sharp, but for others this may be a frustrating problem. If you are using this in a professional environment where accurate focus is key, I would not recommend this, otherwise this is an excellent super wide angle lens for crop sensor DSLRs.

This lens is great, very sharp and nicely built. It's focal length is wide enough that it opens up new possibilities for photography. The ability to capture so much sky and foreground together really takes landscape photos to new heights.

I've been wanting a nice, wide-angle lens for a long time and this totally fits the bill. It's opened up a whole new window of photo opportunities for me. If you're looking for a good wide-angle lens, this one is excellent and at a great price. I'd very much recommend it to anyone.

Great for panarama and wide angle work. Also good for close up photography.

Great for shooting low angles, the ground perspective shots are really great. Close point of focus to infinity are sharp, tack sharp! Excellent lens!

I figured I should snag a super-wide to complement my Sigma 17-70 and Canon 70-200 f/4 L IS before our latest vacation (over to Europe). I thought I could find a use for it there, and it ended up on my Rebel XT most of the time. This lens rocks in most any situation you want where you need a wide view. Awesome in the Alps and in London and Paris. f/4-5.6 isn't fast, but with the short focal range, you can handhold this in darker areas and still get sharp shots.

Images are sharp with stunning contrast and detail, focuses super-fast and silent. Controls are smooth and feel way better than even my 70-200 L(yes, that good). This lens at this price is an incredible bargain. I've found this lens a joy for automotive and fun candids as well. Just get it!

Are you kidding me? For [$] this is an incredible lens! Locally, this lens sells for[$](including tax) so I was more than happy to pick this up online. Adorama ROCKS and so does this lens! I never leave home without it. You won't find a better wide angle for this price. Its excellent for indoor and landscape photography. The shots I get using this lens on my 40D are amazing.

I'm new in the Photo hobby, i be using this lens about 2 month with graet results.

Comments about Sigma Sigma 10mm - 20mm f/4-5.6 EX DC HSM Autofocus Zoom Lens for Canon EOS Digital SLR Cameras.:

I bought a Canon 30D to use as a back up when My Canon 1DS developed a shutter problem. I quickly found my Canon 20-35 zoom was not wide enough because of the 30D's APC sized sensor.

I shoot a lot of interior shots for home builders, so a wide angle is a must.

This lens on the 30D is wider than the 20 on my 1Ds!

It works great and the only complaint I have about it is that you can't use the built in flash on the 30D with it. However, it works fine with my 550EX and my 580EX.

Not at all like I heard about being slow to focus, noisy, and had vigetting. I find the exact opposite

Comments about Sigma Sigma 10mm - 20mm f/4-5.6 EX DC HSM Autofocus Zoom Lens for Canon EOS Digital SLR Cameras.:

This seems to be a very good lens so far. I think it's quite sharp and the build quality is excellent. You tend to use this type of lens at smaller apertures (for depth of field) so I haven't tested it much wide open. It focuses nice and close which is very important for a super wide. Distortion is surprisingly low.

BTW, you can manually pre-focus this lens even when set to auto focus.

I like having the super wide for the perspective. I've taken some nice shots with it already. The idea is to get close. If you can't touch your main subjuct you're probably too far away.

I'm glad I bought this lens. I don't think the Canon would be any better for $200 more.

It met expectations. The Landscape photos are very dramatic.

Absolutely wonderful lens. Exceeds my expectations every time i use it.

Comments about Sigma Sigma 10mm - 20mm f/4-5.6 EX DC HSM Autofocus Zoom Lens for Canon EOS Digital SLR Cameras.:

Very good lens for its class. Good wide angle coverage- equivalent to 16-32mm with my 20D- with little distortion thru most of its range. Some barrel distortion at 10 to 12 mm, especially at wider aperatures, but less than I expected. Very low distortion above 12mm. Canon 10-22mm shows more pronounced distortion at nearly twice the price. Great lens for wide landscape vistas and the distortion at 10mm gives an interesting effect with cloud formations!

Cannot be beat especially at this price!
