2015-03-28T21:00:00
I noticed I reviewed this lens back in 2007, but since have moved entirely to FX and had given this lens to my daughter. This week, I decided to buy a new D7200 as a fun lightweight vacation camera and knew I needed to re-purchase this Sigma 10-20 f/4-5.6 lens because my daughter won't give mine back. Coupled with an older Tamron 17-50 f/2.8, these will be the only DX lenses I'll need to go with my huge selection of FX glass. There's a reason there is such a huge cult following for this Sigma 10-20 f/4-5.6 wide angle and is the reason I am re-buying it. It is just a superb example of this kind of lens. It's very sharp and fairly distortion free. It's 10mm wide end gives me that huge 100 degree field of view I love so much over the years. When used correctly, you can really get in tight with foreground elements while framing the background landscape elements, producing lovely images. The glass is sharp enough to take advantage of today's 24 mp camera sensors providing you do your part. All in all, I highly recommend this lens and the fact that it's so inexpensive is an added bonus.

I use this when I have a limited amount of room to work with. If you aren't familiar with ultra-wide lens, you need to know you can photograph an entire firetruck from about 1 foot away from the front bumper. Very useful when photographing cars, boats, tractor, and the inside of homes if you do real estate. This lens is very sharp if used properly. If outdoors, use the hood. There is no image stabilization on this lens, so you need to use your rule of thumb on shutter speeds or a tripod.

Use the len for travel Take very good pictures Color /tone /sharpness. At 20mm comparable / AS GOOD as my Nikon lens Only drawback: at 10mm little distortion at edge of some picture which is normal for wide angle lens. Overall a very good product with reasonable / affordable price

This lens will help create amazingly colorful landscape shots. The 10mm focal length makes for a surprisingly wide angle that helps you capture the way you see it. A treasure of a lens for the price. Only thing I would improve is faster F-stop but I would expect to pay more for it. Besides, my trusty tripod can make up for low light landscapes needs.

This lens is the most enjoyable lens to shoot with that I have ever used. It makes you work hard to get the best composition, putting the photographer back into photography. Sure, you can use it on a wide vista and 'get it all in there', but the photos are boring. They document a wide field, but unless you are really into this wide open, often empty look, you will not be impressed. Once you get right up next to your prey, THAT'S when this lens shines. There is a little distortion to deal with, but nothing deal-breaking. The photos you get when you take the time to compose and include are stunning. Crisp and clear and loaded with items of interest and real compositional appeal. This lens is an excellent value, especially used.

Works perfectly with D7000, fast focus, sharp wide open at center and very sharp at 8.0. Excellent build quality.

With over 90% of all buyers researching homes BEFORE an on site visit, web based photos a key to selling homes in today's marketplace. This lense gives me the power to present the best story of my clients's home!

Wanted to move into shooting wide angle, and this was a budget friendly way to move into this format. Love it for shooting landscapes and indoors.

I was shooting at sun rise and 20% of my images have green flare. I can't say another lens would do better, but I won't buy another Sigma lens. Please find some place to try this lens before you buy.

Use of the built-in flash causes shadow, but I knew this before buying. Gives me more good/great images in wide angle range. Quality is good to best; works very well on my Nikon D40.

Have only used it once on a trip to the mountains, but so far the lens seems to take sharp photos, even to the edges. The lens cap is a problem, though. The slightest touch will cause it to fall off.

This lens was used on my Nikon D300 up until I upgraded to the Nikon D800. It's a great and affordable lens for aspiring photographers.

Warning to all that may purchase this lens. Although the lens will autofocus,there is no way to lock-in that feature. The gallery photo,the Sigma website description and the instruction booklet that accompanies the lens all show an Autofocus/Manual switch on the base of the lens. It just does not exist.

I purchased the Sigma due to money constraints to place on my Nikon D7000. The lens fits the camera well, focuses without problems and is relatively lightweight. The 77mm cap size is really large, but then it is a wide angle. I have used Sigmas in the past with my Canon SLR/DSLRs and have nothing really negative to say about it.

We have Nikon digital cameras and just love it. Very easy to use, esy to change lenses. Can't say enough good things about it.

This lens merits 5 stars when compared to alternatives. A well constructed , smooth operating performer . No u/wide is optically perfect but c/a is a non-issue , distortion average, and sharpness is generally good.Half the cost of the Nikon , and better build than Nikon and Tamron. Can't beat it.

A little heavy but not enough to bother me. It does what I need it to do and works well.

I have used the lens so far for outdoor wide angle pics. I have, however, taken pics inside with the lens and it captures a much wider view of a room than my 18-55mm.For the price, it can't be beat.

I just received the lens today, but so far in my tests I am absolutely thrilled with it. The clarity is great and I am glad that I went with the Sigma rather than spending twice the amount for a Nikon (which would have been nice, but $$$$).

I bought this for our real estate business. The difference between this lens and the 25-70 that I used previously is like night and day. This is the perfect lens if you need an affordable and high quality lens for architecture.

I was concerned after researching on [...] that some people had an issue with the quality of the glass. I am very happy with this lens for the price compared to the Nikon lenses. I am not a pro so I can't justify paying 1200 for a lens. This is an excellent alternative.

I got this lens primarily for doing real estate interiors, and it works pretty well for that, although it distorts around the edges as most super-wide lenses will do. You have to be very careful about aiming it so that you get your lines straight, so I recommend that you have a good level on your tripod or get an external one to mount on your hot shoe.

Before buying this lens, I must have read a million reviews on line (well, maybe not quite that many). These reviews compared this Sigma lens, the Tokina 12-24; the Tamron 10-24 and the Nikon 10-24. I first concluded that the Nikon was too expensive for my level of photography. It may be a superior lens (at least in cost) but I felt I could go with one of the others to save some $$$. My decision came down to the Tokina 12-24 and the Sigma. Another Tokina lens, the 11-16 is considered by some to be the best of the bunch, but it will not autofocus on my Nikon D5000 so I eliminated it from consideration. Most reviews suggested that the Tokina 12-24 is a slightly better lens, but the Sigma goes wider to 10 mm and since I was buying this lens for landscape and other wide angle shots, I went with the Sigma because of the extra 2 mm at the wide end. I am very happy with this purchase and pleased with the pics I have been taking. Technically, I am sure it is not a perfect lens, but for the money, an excellent value.

I bought this lens for landscapes and I am really looking forward to the fall for more pics.

This is a great lens and compliments my Nikon 18-200mm zoom lens. I am now able to get right up close and capture those weird and wild angle and perspectives that only a ultra wide angle lense can deliver. This was made even better by Adorama's excellent option of purchasing reconditioned lenses in excellent condition at reduced prices. I live in Perth, Western Australia and Adoramas [...]. I am very happy with my experience with Adorama and will be a customer again soon.

A really wide angle lens such as the 10-20 teaches one to see in a new way: composition takes on a new dimension.

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.
Fully compatible with all Nikon Digital SLR cameras including the D40 and D40X, 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.
Please note:
Vignetting will occur if the lens is used with digital cameras with image sensors larger than APS-C size or 35mm SLR cameras.
