Great alternative to Canon EFS 17-55 f.2.8 .......2007-12-12
I purchased this lens after some considerable thought and comparative research against the Canon EFS 17-55 F2.8. While the Canon is a great lens, I couldn't justify the huge difference in price for what seemed to be a very comparative lens in terms of quality and features. Sure, it doesn't have the image stabilization, but in most cases, my problem is not lens shake but rather subject movement (little kids for the most part) and IS doesn't do any good for that. Here is where the 2.8 fixed aperture is great.
I use this as my main lens with a Canon 40D and find it works great as an every day lens. This lense absolutely blows away the Canon EFS 17-85 kit lens that is often paired with the 40D. That lens, although more versatile in terms of focal length, did not seem nearly as high quality and with the much slower speed of the lense (4-5.6), I found myself always having to use the flash.
Overall build-quality is excellent. The lens has a good solid feel to it, but isn't too heavy.
Great lens and a fantastic price.
Be wary of quality control.......2007-12-01
I went through two copies of this lens. The first copy had a front-focus problem approaching 20mm. I sent sample shots to Sigma, and they directed me to simply return the lens to Amazon rather than have it serviced. So, I exchanged it (big points to Amazon for making that so easy!), and the second copy front-focussed by approximately 8mm. That's not nearly as bad, of course, but for close-up photography, it meant few keepers. (I bought this lens for the macro capabilities, as I intended to use it in restaurants, taking pictures of my plate without moving away from the table.) The focus problem was in both my Canon XTi and my Canon 40D. None of my Canon lenses have any focus problems whatsoever; this issue was limited to the Sigma lens.
I sent the lens to Sigma for service, and three weeks later, received my lens back in even worse condition than it started. It still front-focusses by 8mm, and now, even what is "in focus" is much softer than before. I contacted Sigma repeatedly to ask them what I should do, and they ignored my emails.
I have seen many good shots from this lens from people who had good copies. When I shot at f/5.6 or above, I would catch my intended focus point (since the depth of field was increased), but that made shots in lower-light too blurry due to the slower shutter speeds.
This lens can be very good -- if you get a good copy from the start. If you read comments on the photography forums, you'll see story after story of quality control problems from Sigma, and the need for repeated service attempts before a lens will be correctly calibrated. (Several people even report having to send the lens WITH their camera body so the lens could be matched -- even though their camera was correctly calibrated to Canon spec -- being without their camera entirely for several weeks.) If you luck out with a good copy (which is not as likely as it should be), you'll enjoy the lens. If you don't, return it immediately rather than dealing with Sigma service.
The price is low, but the risk is high.
Awesome lens.......2007-11-10
This is an awesome lens. I've had the 1st edition (non-macro) version and even that was nice. This is nicer where the lens is sharper and delivers more vivid color. The macro function is nice and even sharp as well. At 2.8 it's not that sharp, but bump it up a bit to 4, you'll get an amazing result. It also gives you a nice bokeh between 2.8 to 4 for close up photography. Barrel distortion is not that noticeable at the wide end. I just got this lens last Friday and already make a print result of this lens on 40D, 20D and XTI. The close up result is awesome, nice and sharp came out from all 3 cameras. Very nice you can see it at least in 5x7 size. I did notice a loud motor sound when it focuses. I wouldn't care too much if this is just your walk around lens. There is HSM version on this but only available for Nikon at this time.
This will become my walk around lens. I also have Canon EF 24-105 F/4 L for my main wedding lens. Although this is not L quality, I say it's a very nice lens and really close to the L result. I'm not that L junkie anyway. I let go EF 24-70 F2.8 for this lens so I can take it anywhere. I do wedding ocassionaly and I almost lose my neck for holding that beast. That lens is a beast, but very nice though, sharp all the way around. If you have the money, of coarse you'll get the canon 17-55 2.8 IS but I'd rather have a nice weekend vacation with my wife and get this nice, sweet and lite lens. Funny how much I spent on the UV for this with B+W UV MRC, about 1/3 the cost of the lens. But this lens deserves a nice UV.
So guys, if you get this lens enjoy your extra money you've saved for the canon lens. Best bang for your buck......
value is great, quality is not.......2007-08-28
I've bot this lens and was soon disappointed. With all the great value (good zoom range, image quality and 2.8 aperture over the whole range for the price) the lens suffered from terrible front focus on my Digital Rebel XT.
Interestingly enough, my friend's Canon EOS 30D didn't have the problem.
Also I bought the lens through a third-party vendor (47th street photo) on Amazon and hence had troubles reaching them for a return or refund.
So my recommendation is: if buying this lens, make sure to test it right away, keeping all the packaging stuff in case you'll have to return it. I've made some research afterwards and apparently it's quite often to have such problems as I did.
GREAT LENS.......2007-08-27

Sigma 18-50 f2.8 EX DC SLD ELD.......2007-12-28
Purchased the Sigma 18-50mm f2.8 EX DC for use with Pentax K100D Super, mostly for low light photography. Macro and its low light capability are the strongest points of this lens. It also comes with a four year manufacturer's warranty. Great lens. Will recommend.
Great lens :).......2007-11-13
Great lens for low light shooting. I use it mainly for indoor shots. Better option than the Pentax 16-50 2.8 if you're on a budget.
Absolutley Great Lens.......2007-11-05
The Sigma 18-50 f/2.8 EX Macro is an absotuley great lens. Is it perfect? No. Is it as good as primes in the same range? No. But it is darn close to those primes. I have seen and used the Pentax 16-50 and if you need that little bit of added width from 18mm to 16mm, and you do not mind paying another $500.00 for it (and the silent focusing, but not any faster focusing), then buy the Pentax.
This lens gives the photographer sharp photos throughout the range and a fast 2.8 to boot. F/4 and above give the sharpest photos, but even at 2.8 the photos are still very good. Well worth the money I paid for this lens. I would but again if I were to lose this lens or have it stolen (God forbid!).

Pentax 18-50mm.......2007-10-29
Love this lens, very sharp and able to focus on object less than 6" away. Try to find another wide angle lens that will do this for you. Makes great creative shots you could not get otherwise.
Best 18-50 F/2.8 lens for your money.......2007-06-09
I bought the Pentax Mount for my Pentax K10D for indoor use, it is bright, sharp and quick focus, nicely built, it feels solid in your hand, not so heavy, it produce nice bokeh shots. BTW, the Macro is a bonus for this lens. Sigma's technology improves a lot into this F/2.8 Macro lens, for the build quality & Price. I would vote for this lens as "The lens of year 2007". Highly recommended.

It is as I expected.......2007-09-06

Awesome lens.......2007-07-30
I've been using this lens for a little more than a month now and I'm very happy with it.
I use it for weddings, portraits, landscape, and pretty much everything I do. It never comes off my camera. I'm using it with my D80 and I've had no problems at all.
I'm very impressed with the quality and performance of this lens.
BUY IT !.......2007-05-28
This is a really good lent for a great price, F2.8 and Macro for a great quality pictures.BUY IT !
Great Lens. Highly recommend........2007-05-18
Just received this gem and am very happy that I went with it. I have a Sigma 70-200 f2.8 and love it. So, I thought I would try Sigma again. Needed a sharp low light zoom with a semi wide angle for weddings, and presto, this lens fits the bill. I can also take macro shots, which greatly improves the score on this lens. The shots so far have been very sharp with amazing contrast. Only ding for sigma lenses is the stupid lens cap, that does not have the inner grips, so if you use a hood, you have to take it off to remove the lens cap. Simple fix sigma, get with the program. Also, a comparable lens for Nikon is the 17-55 f2.8 which I do not own since it is about $1200 vs the 400 I paid for this, so I have to assume I got a better deal for my needs.
Great upgrade from the kit lens.......2007-05-13
Sharp and solid feeling. Perfect for moderate light when you don't want a flash. Macro capability a +. F2.8 across the range so you can leave manual settings and zoom in and out.
