Sigma 10-20mm f/4-5.6 EX DC HSM Lens for Canon Digital SLR Cameras

After shooting a few months with the kit lens (18-55), I found myself shooting at the wider range more often than not, with the exception of the occasional portrait. So I got rid of the kit lens, got myself a 50mm prime (the f1/4 from Canon: a masterpiece), and a wide-angle zoom for landscapes. I quickly found and bought the Sigma. Two months later, I couldn't be happier. It shoots where no other lens could shoot. Everyone knows that "10mm is wide", but few realize just how wide it is until they see it. Our eyes see in the 40-50mm range, so we're not used to perceiving such a wide field. When you look through this lens, you see pictures that you didn't even know were there. The glass quality is excellent, obviously not up to Canon L standards, but that was never the purpose. The pictures are SHARP and clear, and colors are excellent (tints tend slightly toward the warmer end when compared to Canon's 10-22mm; I like that, personally, but YMMV). Subjects are obviously deformed when shot up close at 10mm, but know what you're doing and that becomes a great tool for artistic pictures! You can shoot a 5'5" person head to toes from less than 3 feet away. Also, I am happy to report that at 20mm there is NO distortion whatever, regardless of the subject's distance. The only problem I can see right now with this lens is a rainbow effect when shooting at 10mm in direct sunlight. The hood helps some, but you'll still get the rainbow in some pictures. See my pic in the customer image section. It's not a huge deal (sometimes it's actually a neat effect), and it's happened to me only once out of 800+ pictures taken, but know what you're getting. Overall, this is THE wide-angle zoom to get if you're halfway serious about landscape photography, although the Sigma also works great in indoors with limited room to shoot.

First off, a wide-angle is sensor specific so there are just a few top contenders for Canon's APC-S (1.6x crop factor) cameras. I shoot with the Canon EOS 40D. The downside here is that if you choose to get a full-frame camera body such as the Canon EOS 5D, you will need to replace this and any other EF-S lenses you own. The Sigma 10-20mm f/4-5.6 has everything I valued going for it: price, build quality, great glass and zoom range. It also comes with a lens hood which the more expensive Canon competitor does not. I rented a couple of comparable lenses to help in my decision: the Tokina 11-16mmf/2.8 and the Canon 10-22m f/3.5-5.6 The Canon 10-22mm, like all EF-S lenses I've used, is built like a toy in comparison to other lenses. Cheap, plastic, loose tolerances. While it did produce OK results, I got vignetting wide open. Considering that its' price is higher than all the rest, it did not look like a good value. The Tokina, on the other hand, was build like a tank. Great contrast, clarity and fast. However, I decided that I didn't need the f/2.8 or the extra $100 on the price tag and did want the extra zoom range. But it is a great lens and you can read my review on the product page. Regardless, I am completely satisfied with this lens and highly recommend it over the Canon.

I was not sure when I ordered this lense what to expect, thinking if I dont like the results, I can return it. I think I am keeping it. I was a non believer, now I am a believer. I did a lot of research as others did and I was a canon lense person all the way. This is a very nice lense good value for the dollar. It feels well made a little heavy but not too heavy, Focuses quick and is quiet. I was at a car show today and took about 150 shots with my 30D, the color was vibrant and the pictures were sharp and clear. I dont use a wide angle enough to justify the canon price, but i think I will be using this more than I expected. If you want a good wide angle lense at a good price for a cropped sensor camera, this is it.

Image Quality: 3.5/5 It is good enough for an ultra wide angle lens, but if you're a pixel peeper, you're eyes will hurt, especially at the edges, where sharpness is nonexistent, distortion is magnified, and chromatic aberration is frequent. Build Quality: 3.8/5 Decent build. Nothing fantastic about it, but it does feel fairly solid. It's mostly plastic, but it doesn't feel like cheap plastic. It is an external zoom, so there's a good chance it'll siphon in some dirt here or there. But it's unlikely that you'll shoot this often enough to have dirt accumulate. Features: 3.8/5 It's got a very smooth zoom and focus rotation. Feels like butter almost, so that's a plus. Has full time manual. Has an AF/MF switch, but that's pretty common these days. Autofocus is good enough (not fast, not slow, accurate enough). HSM is quiet, and I never notice any focusing sounds (doesn't mean that they don't exist - it's just not loud enough to bother me). It does lack OS (optical stabilization), but is that something a wide angle lens really needs? Also, it'd be nice if there were a zoom ring lock. I feel like a lot of people use this lens mostly for its 10mm focal length, but the zoom ring is so smooth that it slips out of place ALL THE TIME. You'll have to get used to checking the ring every time you shoot. That's about all there is to the features. Price: 4.5/5 As for what you get for what you pay, this lens is awesome. You'll find very few lenses out there cheaper than this while offering more. As for the Sigma 10-20mm f/3.5, consider if you really want to pay $150 more for a 3.5. For the most part, I use this to shoot landscapes, which usually requires a fairly narrow aperture (like f/9 or f/16). Also for the most part (99.5% of the time), I use only the 10mm focal length, where you can have the minimum aperture at f/4. So 1/3 of a stop really worth $150? (The answer is no.) Practicality: 3.8/5 I have a hard time using this lens more than 15% of the time. My other two lenses include the Sigma 17-50mm f/2.8 and the Canon 70-200mm f/4. Both lenses are noticeably sharp, even without pixel peeping. Both lenses offer me a variety of focal lengths. Still, I suppose it really depends on the photographer. If you like a wider angle, you may enjoy this lens a lot more than I do (and I still do enjoy this lens). Overall: 3.9/5 Good lens overall. It'd be nice if the lens was sharper overall. Even if corner sharpness can't be corrected, it'd be nice if the center were sharper. A lot of it really does look like rubbish at 100% crop. I'm also not a big fan of the external zoom, but for this price, I'll take it.

This lens is the best quality lens for the price available. What I mean is, out of any cheaper wide angle lenses out there, it would be best to spend the few more dollars for this lens. It comes with a carrying case and hood which is extra nice; considering Canon is charging hundreds more and for whatever reason cannot bring themselves to giving anything away for free. Speaking of Canon, I'm a Canon guy all the way, and this is the first time I considered straying from Canon Products. I'm really glad I did. The reviews on the Canon lens are too iffy to justify paying 200-400 more for roughly the same lens. The photo examples don't give me any justification to pay that kind of extra money either. Some reviews on this lens also seem to be a bit negative, but unless your shooting with the big boys, theres no outstanding reason to upgrade to a more expensive wide angle, as this will cover all of your needs with great clarity and color. The only real fault that is noticeable with this lens is that amount of distortion at the edges at 10mm. This is to be expected with such a wide lens, and can simply be solved by shooting closer to 12mm..etc. However, in some cases, the 10mm distortion actually works in your favor to enhance the height of trees, buildings, and that sort of thing. (Examples of this exist in the photos regarding this lens). Certainly consider reading others reviews, and go to Canon's lens reviews as well, so you can make your own decisions. I just hope this helps in deciding if its worth spending the extra cash for Canon. Happy hunting!

I cannot say that the lens I received most definitely was not used a little bit, but signs of it were completely absent when it arrived. For all I can tell, it was a white box / open box new lens and technically flawless for my intents, solidly meeting my expectations for this lens if I had purchased it new. No branded packaging is included, nor any other accessories or manual, save for the lens covers. It arrived packed well inside the larger Amazon box, followed by a more size appropriate box and wrapped in bubble wrap inside. On an APS-C body, short of an all out fisheye, this lens goes as wide as I need it to go with minimal distortion at the extreme and should work well for me doing real estate and landscape photography. Wide open, it does have very minor barreling, but covers a near perfect 90 degree view, capturing the ground immediately in front of my toes as well as up to level with the horizon when shot in portrait. Don't hesitate to grab one for your first super-wide. You may never need anything else.

When I first got this lens, I really didn't use it all that often. At the same time I purchased this lens, I also purchased the Canon 50mm 1.4. I was so hooked on the professional quality of the 50mm, I completely neglected this lens because it didn't give me the bokeh effect I loved so much with my new Canon lens. I also completely underestimated the sharpness of this lens the first few months. However, if you've been out in the field, or even shooting indoors at home you know sometimes a 50mm just won't cut it, and can be inconvenient in certain situations. This is when I started switching to this lens to accommodate those situations. This is also when, in post production, I realized what it was that I had. This lens is sharp. Not the sharpest, but pretty damn sharp. It's beyond convenient in any environment I'm involved in. The AF when needed on the fly is very fast (and I'm using a T3i Rebel) and makes for some awesome close ups. Naturally a wide angle lens is something you can always have a lot of fun with. The thing I like though is unless I'm REALLY close in the 10-15mm range, it doesn't give too much of that bowl effect actually. If you want that effect you can certain achieve it, but the majority of my shots looks "normal" if you will. I do a lot of Photography for a pet rescue volunteer organization. This lens is my number 1 on site lens now. It allows me to be fast and mobile, and gives me a wide range of options for my shots. I'm always impressed in post production by what I see. I really, couldn't be happier. If you're thinking about it, do it. This lens will warm up to you more and more over time until you completely and utterly fall in love with it.

Purchased this lens about a week ago, when it arrived it was missing the case for the lens that the description said it had. I tried reaching out to the seller through amazon's customer support and seller said this wasn't through them and I need to find the correct seller that sold this. There is no way to contact the seller and when you click on the seller's name, it shows their address in Japan. The only contact info amazon shows is for what seems to be the incorrect seller. I wouldn't trust the seller's product description and what is included. Buyer be ware! On another note, the lens doesn't do that great at autofocus and landscape pictures, which is what I purchased it for. Tried taking pictures with out of the grand canyon and every picture looks blurry and not crystal clear.

Great lens! Really great for landscape shots, or places that are tight quarters. I am a newbie to SLR cameras(t3i) and am not disappointed with the lens at at all. Sharp clear photos. Sturdy well built lens as far as i am concerned(i am not a pro). Shipping was ultra fast ! I would reccomend this lens to anyone that is looking to take group photos as well.

Man erhält für diesen vergleichsweise günstigen Preis, ein Top-Produkt. Man kann mit diesen Brennweiten einfach super kreativ werden. Die lichtstarke Variante F3.5 braucht man nicht, bin ich der Meinung. Aktuelle Kameras haben eine entsprechende Empfindlichkeit. Beim ersten Mal muss man sich etwas trauen die Sonnenblende raufzuschrauben, die geht etwas schwer einzurasten. Es gibt nur einen kleinen Schönheitsfehler und das ist der mitgelieferte Objektivköcher. Erstmal ist das ja echt wunderschön, aber er ist nur bedingt einsetzbar. Wenn man ihn an einen Rucksack macht, so jedenfalls bei mir fällt das Objektiv bei offenem Köcher fast raus, da der Köcher sich zu weit neigt. Außerdem hätte man ihn noch 2cm größer gemacht, würde das Objektiv auch mit aufgeschraubter Sonnenblende reinpassen und man müsste Sie nicht immer umdrehen. Ich nutzte ihn daher nur zum Aufbewahren zu Hause, bin da aber sehr froh ihn zu haben. Die Objektivsäcke der L-Objektive von Canon finde ich da deutlich sinnloser. Habe es jetzt 3 Wochen und super viel Spaß damit gehabt und schöne Bilder gemacht. Verwende es an einer 60d in Kombination mit einem 24-104 F.4 L IS USM von Canon. Diese Objektive ergänzen sich prima. Wer mehr als umgerechnet 168mm Tele braucht, benötigt dann halt noch ein Tele.

Ho acquistato questo grandangolare soprattutto per motivi economici, praticamente è il meno caro ma di media qualità. La qualità migliore secondo me è la costruzione/robustezza, la precisione delle ghiere e il fatto che vengano forniti custodia e paraluce. Il mio obiettivo non soffre di front/back focus (cosa che sembra abbastanza diffusa negli obiettivi sigma) e non presenta nessun difetto. La qualità dell'immagine è eccellente da 12 mm in su, mentre le migliori prestazioni si ottengono tra f8 e f15. A 10 mm noto un leggerissimo sfocato ai lati, ma assolutamente tutto contenuto. L'AF è molto preciso, silenzioso e rapido. Consigliato a chi si vuole avvicinare alla fotografia con un certo interesse. Amazon ottimo come sempre.

J'ai eu l'occasion de tester cette optique et le sigma 10-20mm f3.5 et je doit dire que je n'ai pas remarqué de différence évidente entre les 2 à part le prix... donc au final mon choix s'est porté sur celui ci. + Angle extrême à 10mm et vignetage assez réduit + Bonne résistance au flare + AF rapide et silencieux + Par-soleil et pochette fournis - peu lumineux, difficile à utiliser en intérieur - Filtre de 77mm coûteux mais moins que les 82mm requis sur le f3.5... - Lourd même si moins que le f3.5 Idéal pour les paysages et aussi permet pas mal de créativité une fois que l'on maîtrise la distorsion des perspectives induite par un telle grand angle !
