Product Description

Style: Nikon Digital SLR Cameras

An upgrade to its predecessor, the 18-50mm F2.8-4.5 DC OS HSM is a lens dedicated to digital SLR cameras with APS-C size image sensors offering a large aperture and Sigma’s Optical Stabilization. Once again, Sigma has also engineered the built-in OS function, an anti-shake system, for Sony and Pentax mount allowing the photographer to see a stabilized image in the viewfinder. The combination of the large aperture of F2.8 and anti-shake function makes capturing exceptional photos in low light achievable, and the wide angle is well suited for indoor photography. Two SLD (Special Low Dispersion) glass elements and three Aspherical lenses provide excellent correction for all types of aberrations. The Super Multi-Layer Coating reduces flare and ghosting. Designed with inner focusing and inner zooming systems, high image quality is assured throughout the entire zoom range. The overall length of the lens does not change during focusing and zooming ensuring convenient handling. This lens has a minimum focusing distance of 11.8 inches (30cm) throughout the entire zoom range and a maximum magnification ratio of 1:4.1. The incorporation of HSM (Hyper Sonic Motor) ensures a quiet and high speed auto focus.

I'm using this lens on a Nikon D200. After destroying my 18-200mm Nikon VR I wanted a cheap "walkabout lens" that I could risk destroying as I do a lot of industrial shooting where it's easy to whack a lens.

I bought this lens despite some less than glowing reviews. I really liked the self-contained design where nothing changes length when zooming or focusing. I also liked the idea of it being f/2.8 at the wide end.

This lens has a boatload of chromatic aberration at wider settings which is it's chief drawback. I use Lightroom 2.6 and it's perfectly correctable which enhances its wide end sharpness as well. This lens is sharp enough at all zooms stopped down just a little. It's really quite a surprise. I wouldn't try to make billboards with it, but it should print up to 12x18 with a little care in shooting. The optical stabilization on mine is really very good and I'm impressed with how far it allows me to push the shutter speed on still life shots.

Like most inexpensive wide lenses, it shows corner softness and vignetting at wide settings but this can actually be used to push the viewer into the center of the shot, or vignetting can be corrected in post. Wide open at 50mm (it's full zoom limit) it's soft all over but sharpens up by even F/5.6 on my copy. Not bad since most lenses in this price range are already F/5.6 at this zoom and have to be closed further to get any sharpness at all.

I have a number of Nikon and Sigma lenses and this one sits on my camera almost all the time. I've grown to know and trust it in just the short time I've had it. The autofocus has been very good in low light -- contrary to some reviews I've read elsewhere -- and I have to say this lens is easy to like once you understand its limitations.

For the very low price this lens sells for and the features it has (non-rotating filter mount, internal zoom and focus) it's a very attractive lens for a shooter like myself.

I'm an amateur photographer, whose pictures are taken indoors, with no flash. I could not afford higuer-end class just yet, so I opted for this lens, knowing that 18mm, it gives you f2.8. That is pretty awesome. IT works fantastic and smooth. From the beginning, my photos came out pretty sharp, thanks in part to the Optical Stabilization offered, something that other brands cannot offer for that price.

Strongly recommend this lens for your everyday photos. Outdoors and indoors. It is not heavy, it is fast, sharp, and practical.

Style Name: Canon Digital SLR Cameras Verified Purchase
As a walk-around lens I really did try to think of the best overall lens that I would want. I recently purchased another Canon body (450D) and instead of getting another 18-55 canon kit lens I opted instead to purchase body only this time. I then did my homework on which lens I thought would be best. Looking at the 18-100+ lenses, the 18-200+ lenses, and the typical overpriced L lenses really put things into perspective for me. I love the range of the kit lenses but REALLy wanted a better quality piece of glass, silent AF, and NO lens extension while zooming. This lens fit the bill perfectly! The fact that Sigma not only made the ultimate kit lens upgrade, but also included the petal hood as well for $300 really made me think about my next purchase and Canon.

Canon wants too much money for their lenses and unless you pay the high price for an L lens you don't even get a lens hood! ENOUGH ALREADY! I am sold on Sigma quality and will continue to support them for my future lens purchases. I have now shot over 3,000+ images with this lens and I have only tossed around 15 total.

Extremely Sharp, accurate color, little to no chromatic issues, fast, and sturdy. Buy this lens, you wont regret it!

Test photos made with this lens on a Canon XSI were beautiful.
The photos showed no chromatic abberation or edge distortion.
The colors were true and images sharp as a tack. Depth of field was excellent due to the large aperature.
Large blow up of text revels sharp edges. I would recommend this lens to anyone who likes good quality and price value.

Pro: Stabilizer works very well, built quality is very good, hood fits like a glove.

Con: Focusing is a hit or miss at wider aperture, it's more so than my F2.8 constant Sigma($500), especially at wide end of the zoom.

verdict: can't really complaint about the lens at this price point, it's ten time better build than the NIkon VR 18-55(which i had), and 18-55 Canon IS(which I used), the extra stops is very helpful in some situation.

I was using a Sigma 28-70mm until the diaphragm seized with a friend's wedding a few days away. In the dim light, the large aperture and the optical stabilization proved to be a life-saver. I have a couple of other lenses, but this one hasn't left my camera for weeks, now.

Style Name: Canon Digital SLR Cameras Verified Purchase
I used this lens with my Rebel T2i, and believe me, I really wanted to like it for its $200 price point. Wide-open at f/2.8 (available only at 18mm), I was dumbfounded by how soft the output was. Stopped-down to f/11, the lens exhibits adequate sharpness, but displays high levels of (correctable) distortion. The lens really struggles to resolve any detail in the corners at most focal lengths. I would not recommend this lens to anyone who tends to view images at 100%. Very strong chromatic aberration is visible at all focal lengths, even when stopped down.

Sigma's powder coat looks and feels nice, and the lens has great self-contained zoom action. However, the image quality is downright ugly on an 18MP sensor. I might recommend this lens to anyone with a 12MP or less camera who does not print large or enjoy viewing photos at full resolution. Indeed, the build quality and theoretical features of this lens are appealing, but you really do get what you pay for. CANON USERS: Keep your kit lens for now, it's CONSIDERABLY sharper, I assure you.
