The Sigma 8-16mm F4.5-5.6 DC HSM is the only one of its kind. This is the first ultra wide zoom lens with a minimum focal length of 8mm, designed specifically for APS-C size image sensors. It has an equivalent angle of view of a 12-24mm lens when used on digital camera with an APS-C size image sensor.
Sigma's new FLD glass elements, which have the performance equal to fluorite glass, compensate for color aberration. One hybrid aspherical lens and two glass mold elements give excellent correction for distortion and astigmatism.
An inner focusing system produces high definition images throughout the entire zoom range and the Super Multi-Layer Coating reduces flare and ghosting while superior peripheral brightness ensures high contrast images throughout the entire zoom range.
HSM ensures quiet and high speed AF as well as full-time manual focus capability. It has a minimum focusing distance of 9.4 inches throughout the entire zoom range which allows photographers to emphasize the subject by creating exaggerated perspectives. This lens has a compact construction with an overall length of 4.2 inches and a maximum diameter of 2.9 inches and is perfect for shooting landscape photography, architecture, building interiors, photojournalism, wedding photography, group pictures and more.
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.
The Sigma 8-16mm is commonly used for Landscape/scenery, Weddings and more.The Sigma 8-16mm is most used by customers who consider themselves to be a Photo enthusiast, Semi-pro photographer among others.The Sigma 8-16mm is popular because customers like the following qualities of the Sigma 8-16mm: Consistent output, Durable, Easily interchangeable, Fast / accurate auto-focus, Lightweight and Strong construction

This Sigma lens is one of the best UWA on the market today. In the past, Sigma has had trouble with quality control. It seems to have been mostly taen care of in this lens, with only a few copies that seem to have focus centering issues. While this lens is not the fastest UWA on the market, the aperture is not as much of an issue with UWA's as it is with longer focal lengths. When shooting at 8-16mm, nearly everything is in focus at any aperture. While the f/4.5-5.6 is slow, particularly in ...View full Review
This Sigma lens is one of the best UWA on the market today. In the past, Sigma has had trouble with quality control. It seems to have been mostly taen care of in this lens, with only a few copies that seem to have focus centering issues. While this lens is not the fastest UWA on the market, the aperture is not as much of an issue with UWA's as it is with longer focal lengths. When shooting at 8-16mm, nearly everything is in focus at any aperture. While the f/4.5-5.6 is slow, particularly in low light, it is possible to hand-hold this lens down to approximately 1/4 second exposures due to its wide angle of view, making it good for many situations. The sweet spot of the lens seems to be around f/8 to f/11, but optics produce above average results at all F/stops. The built of the lens is strong and hefty. It is perhaps not up to the build of Nikon Pro glass, but is far better than most Nikon lenses in this price range. The body of it is metal, with plastic/rubber rings. The lens does not extend with zooming or focusing, making the tube far stronger than most zoom lenses. The glass itself extends beyond the edge of the lens, and is protected by the built-in, metal lens hood. This makes it very susceptible to finger prints and dust. I would usually consider this a problem, and would have listed this as a con, but it actually makes the image quality far better than a flat, front element and so I did not consider this a con. While the lens is considered rectilinear, it does have a touch of distortion. The distortion is not even noticed unless there is a straight line near the edge of the frame. If distortion is a problem, it is easy to correct in processing. Autofocus is slightly slow for a UWA lens, considering the slight movement needed for the glass to focus. However, it is not slow enough to notice for normal shooting. Manual focus is very smooth and is easy to adjust. The only problem I have with it is that it rotates in the opposite direction of standard Nikon lenses (not the zoom, only the focusing. The zooming ring rotates in the same direction as Nikon glass). Flare is controlled amazingly well. Most UWA lenses suffer from stray rays entering the lens and reducing the contrast as well as add flare spots. This Sigma handles the flare so well, I was only able to achieve a slight amount of flare, less than that produced by any other lens I've tried, both in the wide and telephoto category. Overall, I would highly recommend this lens to anyone wanting an UWA lens. (Sample included to show flare)

A question was sent to me about using this lens on a Nikon D-90...I have a Nikon D-80 & 7000, and love this lens for both. I've used it on landscapes & cathedrals and while the edges are curved, simply crop that part out. I do not find it has a fisheye effect. I have only used it outside in sunshine & cloudy skies so I can't review it for indoors. I would recommend it if you are looking for an ultra-wide lens for your bag.
Very nice lens. Focus ring is a bit tight but will hopefully loosen up.
Very sharp to the edges, even wide open. Replaced a Tokina 11-16 that need to be stopped down to f/5.6, so no lens speed lost. On the downside, it can't focus infrared, which was important to me. Still a keeper though.
I was a little nervous buying this. I do photography strictly for fun. I am not a pro. I wanted a lens with more of a wide angle than my 28mm. I took this to Cape Cod shortly after I received it and got some great shots of the ocean.
Ordered new lens. Received refurbished lens. Returned refurbished lens. Received refund. Out cost of shipping both ways.
If you're in the market for a very wide angle zoom, this one is certainly worth considering. While there is distortion, that's to be expected with this type lens. The images it produces are, in a word, sharp. Its maximum f-stop tends to make shooting dim interiors difficult without a support
I studied the rave reviews and looked at plenty of examples on-line, so I was disappointed when my lens showed extreme curvature of field at the widest setting. In other words, I could have sharp focus in the center or at the edges but not over the entire image. This problem was actually more pronounced on the the right side than the left. None of the reviewers mentioned this issue, so I returned it. I am still convinced that this is a potentially great lens. if you are looking for the widest possible view for an APS chip camera, there is not other choice. The lens also has a nice finish and a good solid feel.
I use it for almost everything. I love the depth of field. so far nothing I don't like about this lens
I tried the tokina 11-16mm and the focus was soft on that copy so I returned to adorama. When I thought about it, the sweet spot on a lens forces you to stop down anyway so I decided to try the sigma 8-16mm. Very good lens and a better fit for what I am going to use it for mostly which is landscape/vacation photo's and when I need low light permormance indoor's I will just use a tripod.
Just received this lens a few weeks ago. Used it at an outdoor wedding in upstate New York. Photos turned out great. Looking forward to taking this lens on an upcoming trip to San Francisco and Yosemite NP. Lens works well on my Canon 7D.
